OPTIONAL APPLIANCES

The options with boilers and hydronic heating are endless. You can heat your whole house or just a small area, you can heat your domestic hot water with an indirect hot water maker or combine your water heater with solar or heat your house with solar. Use your boiler to heat forced air with a fan coil or use it to heat your bathroom and towels with a towel warmer. Heat your granite or concrete countertops, your driveway or sidewalks, or even your walls. Anything you want, Richfield can give you advise to the best solution. An indirect hot water maker runs off your boiler to provide instant, never ending hot water and the most efficient way to heat a hot water tank. It looks similar to a standard gas or electric hot water tank but the differences are that it does not have a burner or elements, gas line, exhaust or intake air. No mechanical parts and being built from stainless steel means that an indirect hot water maker will last 2-3 times longer than a standard hot water tank. If that’s not good enough, it is also highly efficient and approximately 90-97% while a standard gasfired hot water  tank is about 60-65%. Instead of a burner or electric element, there is a coil that winds and turns throughout the tank. Hot water from the boiler flows through this coil and heats the water indirectly. When water is heated in a tank, particles such as magnesium and calcium get separated from the water and fall to the bottom of the tank forming sludge. A standard gas fired hot water tank has the burner directly on the bottom to heat the water and decreasing the efficiency dramatically when sludge forms(calcium and magnesium). An indirect tank is more likely to be unaffected by the sludge because it does not heat through the bottom of the tank and the cupronickel coil actually “shacks” off calcium and magnesium. The Boiler prioritizesthe indirect heater so when there is a need for domestic hot water, all the boiler concentrates on is heating that tank at full throttle so you never run out of water and then switches back to heating the house after the demand from the tank has been satisfied. A solar panel can be connected to this tank as well and instead of having only one coil from the boiler, the tank has a separate coil from the solar panel. A Fan Coil is similar to a furnace but runs off your boiler instead of a burner. Basically a coil of copper pipes run through the fan coil containing hot water from the boiler and a fan blows air across these coils and heating the air to distribute it throughout the house. The fan coil uses the same sheet metal plenums as a normal furnace, so replacing your furnace with a fan coil is easy. Since there are no moving parts besides the fan, a fan coil can last as long as the house with a fan replacement every 20-25 years approximately. If that’s not going to save enough money then it’s even better to know that a fan coil is less expensive than a furnace as there is no gas valves, gas lines, exhausts or intake air. Humidifiers and air conditioning work the exact way with a fan coil as with a furnace. Fan coils can also be used as garage heaters. The best type(but by no means only type) of fan coil is a hi-velocity system but requires a different sheet metal plenum and distribution system so it is a little more expensive and it is basically limited to new construction.Here is a link to the Hi-Velocity website.
