For homeowners building a new home or undertaking a major renovation, radiant heating with a boiler is worth serious consideration. Most homes in New Britain and the surrounding area use forced-air heating — either a furnace or a heat pump. Forced-air systems work well, but they do have drawbacks: they can be expensive to operate over time, and they tend to dry out indoor air. Radiant heating addresses both issues and offers a level of comfort that many homeowners find noticeably different.
How Boilers Deliver Heat
A boiler works similarly to a water heater, but heats water to a higher temperature. That hot water — or steam in some systems — circulates through a closed loop of pipes connected to radiators, wall panels, or underfloor coils. Because the loop is closed, the water is continuously reused with no waste.
In a conventional boiler, water is heated in a tank and then pumped out through the radiant system. As it moves through the loop, it gradually cools and returns to the boiler to be reheated. The result is consistent, continuous warmth radiating from the floor, walls, or radiators — rather than air being pushed through ducts.
This is an important distinction. With radiant heat, the surrounding surfaces — floors, walls, furniture — absorb and re-emit heat steadily. The room stays at a more consistent temperature, and warmth continues to radiate even after the boiler cycles off. With forced-air heating, rooms begin cooling quickly once the system shuts down, and warm air naturally rises to the ceiling, leaving the floor level cooler.
Types of Boilers
Conventional and System Boilers
Conventional boilers supply hot water only to the radiant heating system. A separate water heater handles the plumbing system’s hot water needs. System boilers include a separate storage cylinder for plumbing hot water, which is connected to but separate from the boiler’s heating loop.
Combination (Combi) Boilers
Combi-boilers have no storage tanks and function similarly to tankless water heaters. Two sets of pipes serve two purposes: one loop for the radiant heating system, and one for on-demand hot water to the plumbing system. Combi-boilers heat water only when needed and prioritize plumbing hot water when both demands occur at the same time.
Radiant Heating Options
Homes can accommodate radiant heat in several ways. Older properties often have metal radiators in each room. Some systems use radiant panels installed in walls or ceilings. The most popular option in newer construction is underfloor heating — coils embedded beneath the floor surface that radiate heat upward, warming the space evenly from the ground up.
The main consideration with underfloor systems and panel installations is the risk of leaks, which can cause water damage that is difficult to detect and repair. Radiators are more straightforward in that regard — leaks are visible and accessible.
