  1. Ohm for Two Tank Systems

  2. Ohm for Single Tank Systems

Is my solar hot water system a fit for Ohm?

  • You need a functioning domestic solar water heating system (not for use with solar pool heating or PV).
  • You need an indoor solar storage tank (here is an example) of 60-120 gallons in capacity.
  • You need to have high speed internet with home router (cable, wi-fi or otherwise).
  • If you have a 2-tank system, simply indicate as much on your order form.

What if I’d prefer to use a professional installer?

Your local solar water heating professional or plumber should be able to install Ohm for a fee. If not, drop us a line and we’ll try our best to find you one.

When will I be charged?

You will only be charged when your Ohm is ready to go - we will confirm your order by email first.

Can I manage my reservation?

Yes! You can control your reservation through Amazon Payments once it is placed.
