Solar Hot Water

A Residential Solar Hot Water system is the most efficient way to save money on oil, propane or electric bills. Living in the Northeast you are going to pay for hot water one way or another. Installing a solar hot water system will cut your costs down 70%-90%. With government tax incentives and rebates offered through the Massachusetts Clean Energy Council, the system will pay for itself in only 4-7 years. Learn more about Rebates and Incentives.  Solar Hot Water can be added to any existing system whether it be a gas fired water heater, an indirect tank or an on-demand unit. Solar hot water can also be installed as a one tank system for maximum efficiency with an electric element or top coil for a domestic hot water backup.  There are many factors that go into the design of a system. Since not all homes are designed the same, not all solar hot water systems are designed the same either. These systems are customized based on your home and your family’s needs. Feel free to contact us for a free quote.  We use the latest technology available to monitor our solar hot water systems. This monitoring allows us to watch the systems 24/7 and even adjust the systems from our office. The customer also has access to the monitoring website so they can view their collector’s production.

Solar Pool Heating

Each year over 130,000 solar pool systems are installed throughout the world with half of these being in the United States. Solar pool systems keep pools warmer longer each season allowing pool owners to use their pool in the shoulder seasons when pools are often too cold. Propane and electric heaters are expensive to operate, maintain and repair. Many of our customers have heaters that no longer work and they are tired of fixing them just to end up with large bills from the utilities for the pleasure of swimming in their pool. A pool is a big investment and Solar pool systems help maximize this investment while reducing pollution and cutting down on costs. Solar is by far the most cost effective way to heat a pool in New England. They are low maintenance systems that utilize the existing pool pump and so do not require additional electricity. The collectors last for decades and the systems can be either stand alone or tied in to an existing heater if desired.

Sizing of a Solar Pool Heating System

Swimming pools gain heat during the day with the suns energy and lose heat at night mostly due to evaporation. More than 70% of heat loss is due to evaporation. This is why calculating the size of the solar pool system is directly related to the pool surface area not the volume of water. The recommended sizing for a target pool temp of 85 degrees is 50% of the pool surface area. For example, a pool that measures 16? by 36? would need 288 sq ft of collector or six 4? by 12? collectors. If the collectors cannot be installed in a due south orientation a larger system might be needed. Indoor pools require a one to one ratio of collector to surface area because they do not get solar gain during the day. For winter pool heating flat plate collectors with a heat exchanger is the best method.

Solar (Radiant) Heating

Solar Hot Water heating is an excellent way to bring Radiant in floor avodart heating-the most comfortable and efficient form of heating together with renewable energy. Our systems are custom designed to heat any size space from a single room or garage to multiple zones throughout the home.  RES offers turnkey systems with the radiant flooring systems and solar components. They can be “solar only” or tied into the homes existing boiler or water heater. Fan convectors can also be used for an alternative to radiant. These fan convectors can be directly heated with the solar collectors or in line with storage.
