Well Life is never dull with an electramate...

The first time I used the heating I depleted the heat store in about 15 minutes, eventually found that the CH pump was at maximum speed not it's lowest. So that now appears to be fixed and I've disabled the on peak charge option as I'm out most of the day so who cares if there is limited heat / hot water until lunchtime.

Next I noticed that my energy meter was not as scary as it used to be only reading 5 Kw off peak. Meaning only one heater is working. Took the cover off and found that the control relay base has melted giving a HR connection to one heater element. Phoned my landlord sent them a picture of the problem and they sent an "electrical engineer" whom I showed the problem to and even left him a DVM to confirm.

Said electrical engineer, who from now on will be called "muppet" proceeded to not fix any of the burnt wiring, melted relay base but to reprogram the off peak time clock to switch the boiler on all day........

Question 1 : Where can the 30A "DuraKool" relays and bases be purchased from in the uk ?

Question 2 : has anyone replaced them both with a pair of contactors,was looking at something like this http://uk.rs-online.com/web/p/contactors/4547783/ and using a pair of contacts for each heater spreading the load and hopefully preventing things melting.

Best to replace with Relpol RG25 relays, fit on same din rail and have good contacts that don't overheat unlike the push in contacts on the original. I also add a relay for the bottom pump on the same din rail to protect the board as when drips develop this pump normally gets water on it which works its way inside which results is a blown board otherwise. Best to turn this pump upside down as well when you are drained down as stops water from any leaks getting inside, just runs off. Pete
