Tankless Combi Boilers in Durango
Two appliances replaced by one box on the wall
A combi boiler does the job of a heating boiler and a water heater. Most of the time it sends hot water through your radiant floors or baseboards. Open a hot tap and it switches over, heating domestic water as it flows, with no storage tank sitting in the basement keeping 50 gallons warm around the clock.
Combis are at their best in condos, townhomes and modest houses, where the mechanical room is small and two showers rarely run at the same moment. A large home with several bathrooms in use at once can outrun one, and there a standard boiler plus its own tankless water heater is often the stronger setup. We’ll tell you which camp your house falls in. We size every combi to your heat load and fixture count, plan for gas line and venting changes, and set the burner for local elevation.
- Hot Water on Demand Heated as you use it, so the tank never runs dry.
- Space Back One compact unit where two appliances used to sit.
- Honest Sizing We’ll say when a combi isn’t the right fit.
Is It Time?
Good reasons to switch to a combi
If several of these describe your home, a combi conversion is worth a look.

Running Out of Hot Water
On-demand heating ends the cold surprise at the end of a shower.
-
High Standby Costs

-
Planning a Remodel

-
Two Systems to Maintain
One annual service covers your heat and your hot water.

Combi boiler questions from Durango homeowners
Will a combi keep up with two showers at once?
It depends on the unit’s size and the temperature of the incoming water, which runs cold here in winter. A properly sized combi can handle a shower and a sink together; two showers plus laundry may outpace a smaller one. We check your fixtures and habits before recommending a model.
Does hard water hurt a combi boiler?
Yes, over time. Minerals in Southwest Colorado water build scale on the heat exchanger, which cuts efficiency and can trigger faults. An annual descale handles most of it. In very hard water, a water softener protects the combi and every other fixture in the house.
Can I convert from a boiler and tank water heater?
Usually. The combi connects to your existing radiant floors or baseboards and to the domestic hot water lines. Some homes need a larger gas line or new venting, which we spot during the free estimate. You’ll know the full scope and price before you decide.
When is a combi the wrong choice?
When a big household runs showers, laundry and the dishwasher together, or the house needs a lot of heat on the coldest nights, one combi can come up short. Splitting the jobs, with a boiler for heat and separate water heating such as a tankless unit, usually handles that better. We’ll recommend what fits how you live.
Can I finance a combi boiler?
Yes. A conversion replaces two appliances, so it’s a larger project, and financing can spread the cost. We start with a free estimate, show you the equipment and installation price up front, and nothing is ordered until you approve it.
