One of the most important steps to a successful zero energy home is to decrease the energy requirement for water heating. There are several alternatives to achieve that. The most common solution is to install a solar water heating system but we also recommend to learn more about the ISOMAX system and zero energy water heaters using the waste heat from our refrigerator, A/C or H/P.
Zero energy water heating systems based on this technology do not require electrical pumps or other electrical components so it is a very cost effective way of providing hot water for daily use.
The instalation of this water heater can save up to 80 % of hot water costs. However, it works only if one of the already mentioned electrical equipment is in use at the same time. Although it can be combined with a preliminary hot water storage.
