The future of heating our homes and businesses is hot water hydronic heating. We are not going to rely on independent single gas burning appliances to heat our homes or supply hot water for our showers. New highly efficient warm air furnaces are not able to vent to the roof as the venter motor is too small. The install of a new furnace sometimes requires a lot of reconstruction in an older home. This adds costs to the job and some unsightly bulk heads in the basements. Water heaters are mostly atmospheric vented (natural draft) but will soon change to direct vent storage or tank less. The word is direct vent which means more vent pipes to the outside walls. If the basement is finished then the cost of reconstruction comes back in adding to the install costs. The solution to the heating of the building residential or commercial is Hydronic Heating. A boiler could heat any building and also supply a heat source for domestic hot water.
Boilers are 95% + today and have an integrated modulation rate, this with the outdoor sensor connected to the outside of the building, this helps control fuel costs and keeps the building from overheating. When it comes to domestic hot water the boilers come with a built in heat exchanger (making the boiler a tank less water heater) or using a pump to circulate the boilers hot water through a coil in a storage tank called an indirect water heater. If a forced air system is required (i.e. removing a furnace from an existing building or new construction with air conditioning) then a fan coil is used , a fan coil is a furnace with a hot water exchanger inside it and no gas burner assembly but essentially operates the same way.
Boilers are sized to match the building’s heat loss requirements. Boilers are available in various size ranges and because they have the integrated modulation rate the operation is very efficient at never burning more fuel than required. This higher efficient operating function allows for lower fuel bills (which means lower carbon taxes as well). Boilers come with many control functions built into the software, the most notable is the outdoor reset. This is a very useful feature because it is always monitoring the outdoor temperature advising the boiler to use more or less heat as the weather changes around us. The boiler is always running at its most efficient state without having to be adjusted manually.
Boilers are multi use equipment, they can heat the entire building, snow melt systems for driveways, decks or walkways, swimming pools and hot tubs, garages and basement floors, forced air fan coils, and of course domestic hot water. Boilers with the use of pumps zone valves and controls can services the entire building’s heating requirements all at once with no delays between functions. All this means is a boiler is a single source heating appliance capable of doing everything we need to heat our buildings and domestic hot water.
In a retrofit of an older home a boiler could connect a fan coil, an indirect water heater, removing the gas furnace and gas water heater. This would give you a very efficient system at about 95%. This is just a start what if we zone the fan coil or we zone the basement with infloor heating add heat to the garage (with a hot water unit heater or infloor heat). We could add a hot tub or swimming pool or if necessary melt the snow off a driveway or walkway, we have no end to the control we could have over how we heat our homes. In the future it may be we only heat the rooms we use and not the ones we don’t, with a boiler we could do that. In today’s innovative market technology is always advancing new products are being introduced every day. Frontier has the newest in innovation today for home heating including the first ever tank less water heater & air handler all in one, what a great advancement.
