A net zero home, or sometimes called zero energy or net zero energy, is a building where the total monthly or annual energy usage is approximately equal to the amount of energy created on-site. There are two major components of a net zero home; the first is having an energy efficient home that lowers the overall power cost required by your day-to-day needs.
And the second is integrating renewable energy resources and methods that will offset that utility usage. Why would anyone want a net zero home? Well, there are quite a few benefits including lower energy costs, less maintenance, greater long term durability, and they’re just more comfortable to live in.
Recently there has been a great deal interest in all electric hydronic heated homes across the country, spurred by California’s commitment to all electric homes powered by renewable electricity and now being discussed and built across the country. The collapse of solar electric panel and storage costs and the rise of superefficient heat pumps make this possible and cost effective.
The goal is to provide a building design with integrated highly efficient electric heating, hot water and cooling solution whose electric demand is low enough for a solar electric system to meet the entire load (and fit the roof).
Air-to-air forced air super-efficient mini split systems with a separate electric hot water heat pump have been available for some time now. Similar solutions are now available for hydronic systems that include hot water supply without the sound, lower efficiency and space demands of standalone heat pump water heaters, or the visual impact of wall mounted mini split terminal units.
Hydronic heat pumps provide far more efficient electric domestic hot water supply than stand-alone heat pump water heaters. (COP 4+ vs COP2), are quieter and require no makeup air. Hydronic distribution is also far more efficient than forced air. Read a detailed explanation here!
Hydronic Heat pumps provide very efficient electric hot water heating and domestic hot water plus chilled water cooling.
Ecowarm can heat a typical space using 90F–105F water temperature for floor systems and using wall and ceiling configurations in the 80F–95F range. Look at the heating capacity chart on Hydronic Heat Pumps and Ecowarm to see what a difference Ecowarm makes for increased hydronic heat pump capacity and efficiency! Ecowarm. A perfect match!
