I am designing a water heater for WFP systems.
My design can be retro fitted to any system and costs nothing to run.
How much would you pay for it?
I am only on prototype 1.
I have designed it only to raise the temp of a 750L tank by 10 or so degrees just now (in preparation for winter) so it is by no means a "hot water system".
If there is enough interest I am sure that the design can be modified to increase the temperature further.
It really is free to run.
Do any of you have a retro fit heater for WFP?
How much did it cost?
Most importantly how much does it cost to run?
Any information would be appreciated.
Thanks.
