Are you not familiar with this on demand water heater?

Expert:  Mike R. replied 2 months ago.

Yes I am. If there is a circulation system then there is a pump. This gets you instant hot water so you do not have to wait. So, is there a pump?

Expert:  Mike R. replied 2 months ago.

Are you getting low flow when running the hot water taps or is it full flow but just cold?

Expert:  Mike R. replied 2 months ago.

I'm sorry that you are having this issue especially as you have guests at your house. I will do my best to help you quickly.Can I ask a couple of questions to help us determine the source of the issue:1. Is the heater displaying any error codes?
2. Can you hear the heater trying to start up?
3. Can you hear a fan running and clicking noises when you turn the hot tap on?This should be a good start to finding out the issue.Looking forward to hearing from you soon.Warm regards
