Boiler Installation

Boiler Installation, the Off Duty Way.

New boiler installations are rare enough in Texas that finding a shop fluent in them is half the project. Whether it is a radiant-floor new build, a hydronic system for a shop, or a replacement bringing a beloved old system into the condensing era, the work is design, piping craft, and combustion respect, and we speak all three.

Installation · Burnet & Central Texas

Hydronic Fluency, Rare and Necessary

Boiler installation is a different discipline from air-side HVAC, and the difference is where projects go wrong: water chemistry that decides the heat exchanger’s lifespan, near-boiler piping geometry that condensing efficiency literally depends on, expansion and circulation design, emitter matching, radiant floors, radiators, baseboards each wanting different temperatures, and combustion venting with no tolerance for improvisation. Around Central Texas the fluency is scarce because the projects are, which leaves boiler owners and radiant dreamers fielding quotes from outfits learning on their dime. Second-generation trade education included hydronics, and this shop keeps the language alive on purpose.

The projects arrive in three shapes. New radiant construction, the Hill Country custom builds and shop floors where in-slab heating starts at the drawing stage, gets designed from heat loss through loop layout to boiler sizing as one system. Replacements bring judgment: matching a modern condensing boiler to an existing loop means verifying the emitters can run condensing-friendly temperatures, correcting near-boiler piping to the new machine’s requirements, and cleaning up whatever chemistry history the old system left behind. And conversions, hydronic where forced air disappointed, get the honest feasibility talk first, because retrofitting water heat into a finished house is real surgery with real costs.

Every install closes with hydronic-specific commissioning: combustion analyzed and tuned, every zone proven under heat, flows balanced, chemistry set with inhibitors, and the documentation, settings, readings, loop maps, filed for the decades the system should serve.

There is also a Hill Country layer to this work that out-of-area advice never accounts for. Limestone terrain around Burnet soaks up heat all day and radiates it back through the evening, so equipment here runs longer and later than the same unit would in a milder market. Humidity rolling off Buchanan, LBJ, and the rest of the Highland Lakes chain works on coils, drain lines, and cabinet steel every month of the year. Then winter shows up sideways: a sixty-degree afternoon collapsing into an overnight freeze finds every marginal component in the county at once. Doing boiler installation correctly here means doing it for this climate, with parts choices and settings that respect what Central Texas actually does to machinery.

Boiler Install Scope, Properly Drawn

What the project actually includes when the shop knows the discipline.

Heat loss and emitter mathThe boiler sized to the building and the emitters’ temperature needs, never to the old nameplate or a guess.
Near-boiler piping done rightPrimary-secondary or direct as the machine requires, with condensing return temperatures engineered rather than hoped.
Venting to the letterModern boilers vent in specific materials at specific slopes to specific terminations. The letter is not negotiable.
Fresh chemistry from day oneSystem cleaned, filled, and inhibited properly, so Hill Country water works for the exchanger instead of against it.
Zones and circulation designedPumps, valves, and controls matched to how the building actually uses heat, balanced and proven.
Combustion commissionedAnalyzer-tuned burn, safeties tested individually, readings recorded. Fuel appliances get full ceremony here.

Same crew, any hour.

The name is the joke, the 24-hour line is not. If this problem cannot wait, call now and the on-call tech picks up, quotes the visit straight, and rolls a stocked truck.

Why Off Duty

Radiant Dreams, Built Honestly

The radiant-floor new build is where boiler installation becomes the best version of itself, and where Central Texas custom construction increasingly looks: in-slab warmth for the stone-and-timber houses, shop floors that make winter projects pleasant, bathroom floors that convert skeptics barefoot. Done at construction stage, radiant is startlingly reasonable, the tubing goes in before the pour, the design work is the real product, and the operating economics of a condensing boiler running low-temperature floors are excellent. We work with owner-builders and contractors from the plans forward: loop layouts, manifold placement, boiler room design, and the controls that make a radiant house feel effortless. The projects are long and the results are the most-loved heating systems we touch.

Replacement customers get a parallel promise: the new boiler will be matched to your actual system rather than dropped onto it. That means emitter temperatures verified against condensing assumptions, pumps and expansion checked rather than inherited, old chemistry flushed rather than sealed in with the new machine, and the near-boiler piping corrected to the manufacturer’s drawing, the difference between a condensing boiler that condenses and one that merely cost like it. The old system’s lessons get read first; the new system gets built on them.

Here is how the visit goes. A call to (512) 925-3090 reaches a real tech, not a call center, at any hour. On site, the diagnosis runs on instruments until the cause is certain, and then everything gets laid out in plain English: what failed, what fixes it, and exactly what it costs, before work begins. When the boiler installation work is done, it gets verified under load instead of switched on and waved at. If the pattern sounds simple, it is. It is also rare enough in this trade that people write reviews about it.

Money talk, handled the Burnet way: we say the price before the work, every time. The trip cost comes over the phone before we roll, the repair quote comes after diagnosis and before a single part goes in, and if the smart move is to not spend money at all, you will hear that too. Fair pricing shows up in every review we have because it is policy, not luck.

A word about waiting it out. Central Texas weather does not leave much grace period, and a system limping in May is a system down in July, when everyone else’s is down too and the schedule is at its tightest. The early call gets the easy appointment and, usually, the smaller invoice. The July call gets the queue. Texas rewards the prepared, and so does our schedule.

Who does the work matters as much as what gets done. Off Duty is owner-operated: the person diagnosing your system is the person whose name carries the company, trained in the family trade and seasoned by ten years of Central Texas installs and repairs. You can see the standard in real job photos, and you will see it again in your own equipment closet.

We run this work all over the map: Burnet and the Highland Lakes first, then the whole hundred-mile circle, Marble Falls, Georgetown, Round Rock, Austin, Killeen, and out to Waco and Boerne. The full sixteen-county roster is on the service areas page. Wherever you sit on it, the same truck standard applies: the same tech, the same instruments, the same price-before-work rule, whether the drive took ten minutes or ninety. Distance changes the arrival window, never the workmanship.

The Standard

How This Work Gets Done Here

Every trade job carries an invisible line item: the standard it was done to. On boiler installation work, ours reads like this. The diagnosis is proven with instruments, because guessing is expensive and it is your money on the table. The parts that go in are parts we would put in our own house, matched to spec instead of whatever was cheapest on the shelf. The workmanship follows the manufacturer’s book and the Texas code book both, because shortcuts hide for exactly one season and then bill you with interest.

When the work is finished, it gets tested the way it will actually be used: under load, at temperature, with the readings written down. Then the area gets left the way we found it or cleaner, the old parts get shown to you on request, and the invoice matches the number you already heard. If anything acts up afterward, you call the same number and the same person answers. That is the entire warranty conversation most customers ever need, and it is why the reviews keep saying the same three things: honest, fair, showed up.

Boiler Installation Questions

Asked Before We Roll a Truck

The ones the phone line hears most for this service, with the answers given at full length instead of sales-brochure length.

Does anyone really install new boilers in Texas?

We do, regularly enough to stay fluent: radiant new construction in the Hill Country custom market, shop and outbuilding hydronics, replacements for the existing boiler fleet scattered through older homes and ranch properties, and the occasional forced-air refugee who has felt radiant heat somewhere and wants it at home. The rarity is exactly why the shop choice matters, hydronic design mistakes are expensive and slow to surface, and why our quotes read differently: heat loss math, emitter analysis, piping diagrams. If you have been collecting shrugs from air-side contractors, this is the right phone number.

What is a condensing boiler and is it worth it?

A boiler that captures extra heat by condensing water vapor out of its own exhaust, pushing efficiency into the mid-nineties where conventional units live in the low eighties. The catch is thermodynamic: condensing happens when return water comes back cool, which radiant floors deliver naturally and high-temperature radiator loops only partially, so the honest efficiency projection depends on your emitters, and we calculate rather than brochure it. For radiant systems the condensing choice is nearly automatic; for radiator retrofits we run the numbers and design the piping to harvest what your system can. Worth it usually, and provably.

Can you add radiant floor heat to my existing house?

Honestly: sometimes, with the feasibility conversation up front. New construction and additions, absolutely, and slab-stage timing makes it reasonable. Existing houses fork by construction: remodels opening floors anyway create real opportunities, staple-up radiant under accessible wood floors works with proper design, and bathroom-scale projects during renovations are a favorite gateway. Finished slab-on-grade houses are the hard case, overpour and floor-height implications make it major surgery, and we say so rather than romance it. The walkthrough sorts your house into its honest category, with alternatives, including ductless zones, priced alongside.

How long does a boiler installation take?

Replacements onto healthy existing loops: typically two to three working days, covering removal, piping corrections, venting, chemistry, and the commissioning ceremony. New radiant systems run on construction timelines, tubing and manifolds at slab stage, boiler room fit-out later, coordinated with the build rather than counted in days. Conversions price and schedule by scope after the feasibility walk. Heating is never left off overnight in cold weather without an agreed plan, and no boiler leaves our hands without analyzer-tuned combustion and every zone proven warm, which is the part of the schedule that never compresses.

What maintenance will a new boiler need?

An annual service, ideally each fall, and the modern condensing units add their own item: condensate handling, the mildly acidic drain from efficient combustion, gets neutralized and kept clear. Otherwise the rhythm matches boiler tradition: combustion re-analyzed, safeties tested, chemistry checked and topped with inhibitor, circulation and expansion verified, heat exchanger inspected. Our installs leave with the first fall visit scheduled and the system documented, and the boiler that gets that yearly hour of attention is the twenty-year kind. The one that skips it becomes a repair-page character instead.
