1. Simpler & cheaper to buy and install than solar, tankless or geothermic.
-
2. Works with any of those, and with any other type of water heater, to reduce size, cost and energy needs.
-
3. Drainergy works 24/7 all day all night all year for fast payback.
-
4. Any diameter any length, no pressure drop.
-
5. No power, no moving parts, no maintenance, double walled and vented.
-
6. Stored heat is protected from cold drainwater.
-
7. High performance from very high pressure contact over the entire heat exchange surface.
-
8. Installs in new or existing buildings - even over drainpipes that remain in operation!
Drainergy pre-heats cold water going to the water heater for free.
This pre-heating means:
-
more hot water is available -
less energy is used
-
less money is spent
-
less pollution is released
-
peak power demand is lowered
