Space and water heating are the two most
energy consumptive processes in your home, and in turn, produce the most
greenhouse gases. Taking the time to research and design an efficient space and
water heating system for your home will pay great dividends in terms of lower
monthly energy bills and increased comfort - two of the most lasting
impressions of any home.
With a geothermal heat pump, you can tap into the already existing
limitless supply of carbon-free, naturally occurring heat stored beneath your
feet. This eliminates upwards of 70-80% of the costs associated with space
heating simply because you don’t have to make the heat – it
already exists. You just have to move it from one place to another, i.e. from
the ground to your home.
To move this free heat around your home you have two choices: air or
water. Most people know that warm air rises – and in your home that
means to the ceiling. So, with a forced-air system, your home is effectively
heated from the top down. Heat, on the other hand, radiates in all directions,
and with a radiant floor heating system your home is heated from the ground up.
Not only is this a more efficient way to heat your home, people feel equally
comfortable at lower operating temperatures, further increasing your energy
savings.
As for heating your hot water, a geothermal system can also be fitted
with a hot water generator (a ‘de-super heater’) to
supplement between 45-75% of your hot water demand. Similarly, using clean,
renewable solar energy to cost-effectively heat your water could also, by
itself, supplement up to 60% of your hot water needs. And, of course, combined
they can often provide all of the hot water your family will need for a
dishwasher, washing machine, and showers. |
