Hello everyone,

I was thinking - during the coldest months when my house temperature is sometimes a touch colder than ideal - of using the excess solar I often have to run an inline water heater, something like this:

 

1kW inline water heater

 

I can set up my Victron system to run that heater when the batteries are at 95% SOC or above (which is quite often). 
 

Currently the UFH isn't used much - maybe 20 days out of the year. It runs through my combi boiler and works really well just utilising a room thermostat to activate it early in the morning if the house temp drops below 18 degrees. 

 

Any thoughts on issues with me doing this?

Plenty of threads on Willis heater - basically the same as you have linked too but less than half the price.

That is a Willis heater. Can't find anything on here using search, will have a look on the general www.

The Forum's built in search engine to truly appalling.

I find a proper search engine doing a site search is much better.
