Central Heating Installation
Boiler, combi, and radiator installation for homes with existing central heating in Johnston, RI and across Rhode Island. Honest pricing, RI-licensed plumbers, no upsell on systems you don't need.
Based in Johnston, RI, our team installs the components that make up a modern central heating system — new boilers, combi units, radiators, circulator pumps, zone valves, and controls — on homes that already have central heating distribution in place. If your house has radiators or hydronic baseboard but the system is tired, inefficient, or running on the wrong fuel, this is the work we do every week across Johnston and the surrounding Rhode Island towns.
Most of what we install in Johnston-area homes falls into a few clear categories: replacing an aging oil boiler with a high-efficiency gas unit on an existing radiator loop, swapping out a tired boiler-and-water-heater pair for a single combi system, installing new radiators or baseboard sections during a remodel, and bringing old single-zone systems up to modern multi-zone control. Every installation is sized to your house — your square footage, your existing distribution, your real hot-water demand — not pushed onto you because we happen to stock one brand.
What we don't do: build a brand-new central heating system into a house that has never had one. If you have forced-air-only or no central heating distribution at all and want to add a full hydronic system from scratch, that's a different specialist. We'll tell you straight rather than take a job we shouldn't.
All installation work is performed by Rhode Island licensed plumbers, with gas work handled under RI gas-fitter licensing. We pull the right permits with the town of Johnston (or your municipality), coordinate the inspection, and document the install so your warranty and any utility rebates go through cleanly.

What to Expect from Central Heating
Boiler, combi, and radiator installation for homes with existing central heating in Johnston, RI and across Rhode Island. Honest pricing, RI-licensed plumbers, no upsell on systems you don't need.
New Boiler Installations on Existing Systems
The most common central heating installation we do for Johnston homeowners is a boiler replacement on a system that already has working radiators or hydronic baseboard. The old unit is past its efficiency window, parts are getting hard to find, or the fuel bill has crept up to the point where the math on a swap makes sense.
What we install most often in this category:
- High-efficiency gas boilers (modulating-condensing where the application supports it) to replace older atmospheric or chimney-vented units
- Cast-iron boilers where the home's existing chimney and venting are best matched to that style
- Propane-fired boilers for homes in the more rural pockets of north-western Rhode Island that aren't on a gas main
- Indirect-fired water heaters paired with a new boiler for combined heat and hot water
Every Johnston-area boiler install includes a heat-loss calculation so the unit is sized to your house, full combustion testing on commissioning, and the municipal permit and inspection pulled and closed out on your behalf.
Combi Conversions and Fuel-Source Changes
Two installation projects that come up often in older Johnston housing: combi-boiler conversions and oil-to-gas source swaps. Both keep the existing radiator or baseboard distribution in place — the work is concentrated at the boiler and water-heater side.
Combi boiler installs. A combi unit handles both space heating and domestic hot water in a single appliance, so we can remove the old boiler and the old tank water heater and replace the pair with one wall-mounted unit. The wins are smaller footprint, no standby hot-water loss, and modulating efficiency. We size combis to your real fixture-count demand — a four-bathroom house needs more capacity than a one-bathroom ranch, and we won't undersize you to save a few hundred dollars on the equipment.
Oil-to-gas conversions. If your house already has hydronic distribution and a natural-gas main on the street, swapping the oil burner for a gas boiler usually pays back over a handful of winters. We handle the boiler swap, the gas-line extension to the unit, the new venting, the disconnection and pump-out coordination for the oil tank if you want it removed, and the utility coordination on the new gas service tap.
Components and Systems We Install
New gas or propane boilers — high-efficiency condensing and cast-iron, sized via proper heat-loss calculation Combi boilers replacing tired boiler + water heater pairs in one wall-mounted unit Replacement radiators and hydronic baseboard sections on existing loops Indirect-fired water heaters paired with a new boiler for shared efficiency Circulator pumps, zone valves, and zone controllers on existing distribution Expansion tanks, low-water cutoffs, and modern safety controls Smart and programmable thermostats wired and configured to the new system Gas line extensions and venting (concentric, sidewall, and chimney) to suit the install
Zoning and Control Upgrades During Installation
If we're already in the basement installing a new boiler, the cheapest time to upgrade an outdated single-zone system to proper multi-zone control is right now. We routinely add or improve zoning during a Johnston boiler install when it makes sense for the house.
- Splitting a single-zone house into upstairs/downstairs zones so bedrooms don't roast at night while the living room stays comfortable
- Adding dedicated zones for finished basements or additions that were tacked onto the original heating loop
- Installing modern zone valves and zone controllers to replace failing 30-year-old mechanical setups
- Pairing the new boiler with smart thermostats per zone for remote control and per-room scheduling
None of this is required. If you're happy with the way the house heats and just want a quiet swap of the boiler, that's exactly what we'll do.
Central Heating Installation Questions We Get
Do you install central heating in a house that doesn't currently have it?
No. If your home has no existing radiators or hydronic baseboard and you want a full central heating system built from scratch, that's a different trade specialty. What we install is on systems that already have distribution in place.
How long does a boiler replacement take in a typical Johnston home?
Most straight boiler swaps on an existing system are one to two days on-site, plus the inspection visit. Combi conversions and oil-to-gas swaps are usually two to three days. We'll give you a realistic timeline when we quote, not a marketing answer.
Will my house be without heat during the install?
For scheduled work outside the coldest months, we do the change-over in a single workday so you only lose heat for a few hours mid-day. If we're working through January cold, we plan a heat-source bridge (space heaters, temporary connection) so the house stays comfortable while the new system is commissioned.
What sizing approach do you use?
Manual J heat-loss calculation for new equipment, sanity-checked against the existing distribution. Oversizing a residential boiler is one of the most common installation mistakes in our industry — bigger is not better, it cycles harder and runs less efficiently. We size to the house.
Do you handle permits and inspections in Johnston?
Yes. Permits are pulled with the town of Johnston (or your municipality if you're outside Johnston), inspection is scheduled, and we close out the paperwork. Included in the quoted price, not a hidden add-on.
Are you licensed in Rhode Island?
Yes. All boiler and plumbing work is performed under Rhode Island plumbing licensing, with gas work handled under RI gas-fitter licensing. We're not a UK-based contractor and we don't use UK certifications — RI homes get RI-licensed plumbers.
What utility rebates apply?
Rhode Island Energy offers rebates on qualifying high-efficiency gas equipment, and federal tax credits apply to some condensing units. We provide the documentation you need to submit the rebate or credit yourself — we don't process the paperwork for you but we make sure you have everything to do it.
