Hydronic heating

...water heated , so don't let this irritating trait put you off them. One advantage to hydronic heating systems is the ability to convert to thermal solar in the future. Solar water heating is much less expensive than solar power generation (photovoltaic) . New homes can be made 'solar ready' which is very inexpensiv...

Solar Radiant Heated Floor Slab Kit
Delivery: radiant, forced-air and decentralized

Solar heated radiant floor with radiant heated hot water for a site with problem soil - expansive clay

...solar panels (compared to photovoltaic panels) to harness the energy of the sun to heat garages and workshops, but solar radiant air-heating has yet to be a viable and reliable option for well-balanced home heating. Until now …. When looking for a heat-storage solution that would allow us to incorporate solar-air hea...

Solar thermal collectors

Product of the month: Solar water heater with overheating protection

...water heating, swimming pool heating, or in conjunction with hydronic radiant heaters or radiant floors. The percentage of your heating demand that a collector will provide in any situation depends on solar availability and consumption; meaning, how efficient your home is, how big your pool is or how much hot water you...

All about solar thermal collectors

...solar radiation. That can be as simple and rudimentary as water being pumped through a black tube laying in the sun. There are countless DIY solar panel designs to be found on the web, but there are commercially available solar-thermal panels that can be used for water heating and space heating. A thermal solar colle...

Where to place solar panels

...heating water or air the additional heat may not be desired.) The earth orbits the sun in an elliptical cycle becoming closest to the sun on the winter solstice resulting in the greater solar irradiance (the amount of solar radiation striking a surface). For this reason, solar thermal panels can experience the most...

Solar heating and energy generation

...Solar thermal heating and solar water heaters This refers to using solar panels to absorb heat in a liquid (mix of glycol and water) and redistribute it throughout the house, through radiators or radiant floor heat. A system can work to heat your home, as well as pre-heating your domestic hot water. It can ea...

The Kenogami House: Energy systems in Net Zero Energy Home Design

...solar PV powered air to water heatpump to put heat into the radiant floor heating in the slab foundation. Heating water with PV instead of thermal solar panels: It may seem counterintuitive at first, but there is strong case supporting the use of PV panels for heating water over thermal solar systems in Net Zero En...

Increased efficiency with heat pumps working in tandem

...water heater from AO Smith is an air-to-water heat pump which extracts heat from the air to generate hot water, so in the winter that 3 to 1 heating ratio of the first heat pump is transferred to the water heater. And the more 'free' heat you have in winter (solar gains and general occupancy) the more efficient it be...

First Passive House in BC Whistler

B.C.’s First Passive House was built in Whistler in 2012.

...solar home is designed to absorb as much of the sun’s heat as possible in the winter months, without over heating in summer months. Solar hot water collection, a subsoil heat exchanger and cross-laminated timber decking are a few of the extensive sustainable building features incorporated into the prefabricated design,...

...solar thermal panels. Even this type of system is not new, the first house in the United States with an active solar heating system was built In 1939 on the MIT campus (Massachusetts Institute of Technology), and sat on top of a huge water reservoir that was heated by thermal solar panels. MIT Solar House thermal...

...solar panels. Solar heating is essentially free (there are some small increases in electricity for the costs of pumping water through larger solar panels, but it is minimal as this links to the pool filtration system anyhow if planned and built right.) The downside of solar, especially in more northern areas, is that i...
