Multi Energy source hot water cylinders are becoming more common in big new homes. Basically treating the large Hot Water Cylinder like a battery or storage device for heat sometimes up to 500 litres and in some rare cases 1000 litres.
There are some smaller versions just for use with fire and wetback system and solar.
With multiple connections and heat exchanger coils inside the HWC it able to exchange heat between different methods of heating such as Solar Hot water heating (with this type of system the collector can be much larger) gas boilers, solid fuel or wood boilers or large wetback fireplaces and hot water heat pumps (HPHW) to name a few.
The domestic water supply is held in this large tank and is heated by many efficient methods. It is kept separate from the heating systems in most cases as they are working at different temperatures and pressures. Some of them will have a glycol fluid circulating that is not pleasant or hygienic to drink or bathe in; hence the domestic water is kept separate and sanitary.
The main purpose of these large systems is to heat the home through underfloor heating or radiator systems as well as heat the domestic water supply. In some cases the swimming pool can be connected if the solar system is set up as a drain back system.
It is specialised work to install these systems and to have safe control over the energy being sent to the hot water system. We are often called to install this part of a new home build while working in with the existing plumber onsite.
We are called in to sort out a lot of the currently poorly installed systems around the area. If this is you please get in contact.
