Residential Heating

Heating is the largest energy expense in most homes, accounting for almost two-thirds of annual energy bills in colder areas of the country. Heating systems in the United States emit a billion tons of carbon dioxide (CO2) and about 12% of the sulfur dioxide and nitrogen oxides emitted by the nation. Reducing energy use for heating is the single most effective way to reduce your home's contribution to global environmental problems.

If your furnace or boiler is old, worn out, inefficient, or significantly oversized, the simplest solution is to replace it with a modern high-efficiency model. Gas furnaces without electronic (pilot-less) ignition, are prime candidates for replacement.

Gas Furnace

Trane Logo Every model in Trane furnace family we carry, is designed to provide maximum heat for minimum fuel usage. The furnaces have AFUE ratings from 80% up to 97.3% which means that at least 80% or more of the fuel you pay for is actually converted into heat for your home.

As you climb the ladder from single-stage, to two-stage, Two-Stage/Variable speed (Comfort-R™), and Modulating furnaces, you'll find an increasing number of benefits along the way. For example, two-stage heating provides just the right amount of warmth, frequently operating in low heat, which is often all that you need. Comfort-R™ furnaces are perfect for circulating air at all times. This keeps all rooms in the house at an even temperature, even when heating and cooling are not running. In addition, this continuous fan feature allows you to scrub your air 24 / 7, supplying you with clean, healthy air to breathe all year long. Comfort-R™ furnaces provide even temperature and non-stop filtration for about the cost of low wattage light bulb

High Efficient, Condensing Furnaces

Boiler (Hydronic)

Indoor Air Quality

A home heated by hydronics can have excellent indoor air quality. One reason is because the system uses the natural convection movements of heated air to distribute heat - it's not "blowing" air to other parts of the house. This tends to create a friendlier environment for those who are bothered by particles in the air. Particles and dust have a chance to settle out of the convected stream of air because it moves so slowly.

Heating and cooling typically accounts for 30 to 40% of your annual energy bill. Next to furnaces, boilers are the second most common heating system in the United States. A boiler uses natural gas to heat water or produce steam, which is circulated through a network of pipes into radiators, baseboard convectors, radiant floors or fan-forced coils.

Boiler efficiencies have been improved with AFUEs of ranging from 84% up to 96%. You can see that with this level of increased efficiency, the opportunity to save a lot of energy is even greater.

Conventional, older boiler systems may only be 60% efficient. By upgrading to a new boiler, you could save considerable amounts of money on heating throughout the life of the new equipment.

Added Benefit of a Boiler System

An added advantage of a boiler system is you a heat your domestic hot water and eliminate the need for a separate hot water heater. By attaching a "sidearm" (Water Tank) to the boiler system you will be able to heat water with a system that is much more efficient than a standard water tank. A sidearm offers a virtually limitless supply of hot water because of the higher recovery rate of a sidearm setup.

A sidearm water heater is like a combination of a tankless water heater and a storage tank water heater. Sidearm water heaters use the boiler to heat the water. Similar to a storage tank water heater sidearms store hot water around 120-140°F. When a fixture is turned on cold water replenishes the hot water in the tank. The difference with a sidearm is that, instead of having a burner to heat the water in the tank, there are coils in the tank which are heated by the boiler. The coils heat the water in the tank.

The benefit to a sidearm water heater is a near endless hot water supply like a tankless water heater. In addition to that, since there is no vent, there is no heat loss through the vent.

Infra-Red Heat

How infra-red cuts costs

Infra-red heaters cut fuel costs by lower temperature settings - Building heat loss is in direct proportion to the difference between the inside and the outside temperatures. With RE-VERBER-RAY®, the heat is directed to the floor and not trapped at the ceiling. Therefore, you can lower thermostat settings between 5 and 10 degrees and still maintain desired comfort levels at the floor.

Heater Installed What is Infra-Red Heating?
Infra-red heating emulates the truly inexpensive efficiency of the sun. Like the sun, infra-red heaters generate radiant heat energy that is converted into heat when absorbed by floors, objects and people. Absorbed heat is then "re-radiated" to warm the surroundings through convection.

Comfort & Energy Saving
The popularity of these types of heating systems is a result of two inherent benefits. Gas fired infra-red heating has been proven time and time again to be significantly more fuel efficient than traditional hot air type systems.

Fuel savings of 50% over hot air systems are not uncommon. The other reason for their popularity is the superior comfort levels achieved with their use. Infra-red heaters concentrate the heat at the occupation levels and utilize the floor and objects in the space as heat sinks which reradiate heat to the surrounding air. Hot air type systems deliver a blast of hot air to the floor level that quickly rises to the ceiling. In order to maintain a comfort level at the occupation level, the use of traditional hot air systems can result in extremely high temperatures at the ceiling.
