I was wondering if i could heat the water in my swimming pool using the heat in the house s attic and i started messing about with a large s heatsink s thermal battery.
Geyting hot water from your attic.
Within the attic insulation is a must.
You won t ever pay an energy bill for that unlike you do with your pav.
Your attic can easily reach temperatures of 120 140 degrees which is optimum for keeping the water in your tank sufficiently hot without using any energy.
Now a secondary line of reasoning for placing a water heater in the attic is the high temperatures that occur in an attic particularly during the summer months.
If you want to put a powered attic ventilator in your house fine.
Poor insulation is usually the culprit although if you enter the attic on sunny winter day your attic space can be warmed by the sun more than your furnace.
You d be better off insulating and air sealing your ceiling.
There is an electric pump next to the water heater that moves the hot water through the pipes delivering hot water quickly to most any faucet.
Unless your roofing system has insulation on the roofing deck and is designed without ventilation your furnace should not be heating your attic.
In addition hot air in your attic could increase moisture levels which could result in wood rot and mold growth.
Alternatively install passive vents such as gable soffit and ridge vents which are openings in the roof that allow hot air to escape.
Having a properly vented attic is the best way to keep attic cool because it allows the hot air to escape during the summer.
Install electric ventilators and attic fans which remove hot air from an attic.
If you want the heat out of your attic a reflective roof or radiant barrier are better ways to get there.
A good way to gage if more insulation is necessary is to look in your attic for ceiling rafters.
Turn excess attic heat into hotwater.
They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees.
A thick insulation between 14 to 18 inches will help reduce heat from entering your home.
If hot air is allowed to sit in your attic it could overheat the shingles on your roof and cause damage.
