Forced Hot Water Heating

This type of system has a boiler for a heat source and heats the water inside the boiler. The heated water is sent up pipes throughout the house by either circulator pumps or zone valves. Fins in the baseboard then disperse the heat throughout the house.

Advantages

Provides fairly even heat with little to no drafts. It allows for domestic hot water production without a separate burner for the hot water tank.

Disadvantages

The system does not allow for air conditioning, air humidification or air filtration without adding ductwork and an air handler.

Key System Features

  • AFUE
    Annual Fuel Utilization Efficiency. AFUE is a rating that reflects how efficiently heating system converts fuel to energy.
  • CONDENSING BOILER
    Condensing boilers are far more energy-efficient than conventional boilers, as they reuse heat that would otherwise be wasted. Some heat generated by conventional boilers disappears up the flue in the form of hot waste gases. But condensing boilers use some of the heat from the flue gases to heat water, making the boiler far more efficient.
  • OUTDOOR RESET CONTROL
    Outdoor reset is a weather-responsive control. Based on changes in outdoor temperature, it automatically adjusts boiler water temperature. If the temperature is colder outside, it takes more heat to overcome its effect inside the building than if the weather is warmer! Outdoor reset is the same as turning down the boiler water aquastat in the spring and fall — automatically. Outdoor reset is an essential part of advanced boilers. It makes it possible to have only as much stand-by heat as the weather demands. This increases energy efficiency and comfort. And outdoor reset makes it more likely to have the cool return water temperatures required for condensing boilers to perform up to efficiency expectations.
  • STACKABLE WATER TANK OPTION
    Short on space? Stack your boiler on top of your water tank.

Case Study – Forced Hot Water Heating

Conversion of heating system from oil to gas

It wasn’t so long ago that we all experienced insanely high oil prices, making us keenly aware of various ways to become more energy-efficient. One of our customers asked us to replace their old oil boiler with a natural gas fired forced hot water system. We looked at their basement and saw that it was being used as a recreation room, as well as the place where the boiler resided.

To save space (and make more room for recreation), Wilson Brothers recommended a wall-hung unit by Buderus. It is ultra efficient and whisper quiet with a fully enclosed housing. It includes an outdoor reset control that features a sensor to monitor the outside temperature. This reset control uses the outdoor temperature to calculate the water temperature required to provide the heat necessary to make your home comfortable. The system adjusts before you even feel too cold or too warm!

This is the ultimate in comfort, but it also is energy efficient resulting in lower heating bills. It also makes living “green” a bit easier! In addition, the system was eligible for a tax credit of 30% of the installed cost (up to $1,500) and a $1,000 rebate from the Gas Company.
