Comparing ground source and air source heat pumps
Heating and cooling

Heat Pumps: Ground source geothermal GSHP or air source ASHP, which one is best for heating a home?

...Heating Systems and you will find hundreds maybe thousands of companies using the word "Geothermal" to describe ground source heat pumps, two systems that have only one thing in common: they sit on and in the ground. Even government organizations muddy the story by calling them "geothermal heat pumps." Real Geotherma...

Passive house and passive solar - free heat for homes

...Heating & Cooling? Passive heating and cooling of homes is not new . The above image is of Mesa Verde National Park, the Ancestral Puebloan cliff dwellings in Colorado, occupied from 700 to 1300 AD. This early North American settlement was shaded from the summer sun, but fully exposed to the sun in winter, which woul...

Are tankless water heaters good?

...systems that do not include the storage tank that comes with traditional water heaters. This type of water heating system can be advantageous in some climates, provided they use gas-fired as opposed to electrical heating. These heaters may also be known as ' inline water heaters', 'continuous flow heaters', 'instanta...

Heat pumps: what they are and how they work

...heating and cooling systems, few types of systems are as energy efficient as heat pumps. But what exactly are they and how do they work? In short, a heat pump is simply an electrical device that is capable of transferring heat from one place to another. Though it may seem counterintuitive at first, heat can actually be...

Off-grid and Net-Zero Housing

Thinking about renewable home energy and a battery backup?

...heating by that same amount and suddenly heating a house with an active solar panel system becomes more realistic. Even more so if you design for passive heating as well, which can potentially cut demand in half on its own. It is our humble opinion that financial resources are often squandered in home construction wh...

Ecohome Demo House: High performance, affordable cost

...heating systems and the utility bills that come with them. When a design team focuses on heat retention rather than heat generation, the net result can be a home that is cheaper to own and operate; not far into the future but right from day one. Added building costs are offset monthly by lower heating costs, and expe...

Efficient home design, or how to design a home to use less energy

...systems designed by a heating and cooling contractor, have it done by an engineer. Heating contractors typically install over-sized systems to protect themselves from complaints of insufficient heat. The result is a system that starts and stops more frequently, so it never runs at its most efficient rate. Think of that...
