If a rod stat is replaced does it have to be gledhill replacement?

Any advice on the following situation would be greatly appreciated....

A few months ago out pulsacoil 2000 overheated really badly causing it to steam and damage the door frame of the cupboard it was in. The header tank was also empty. So an engineer replaced the pump, as it was sticking. And replaced the off peak rod stat assuming it was faulty causing it to overheat. The header tank was also filled.

However, since then the off peak provides only a limited amount of hot water. Enough for two short showers in the morning but by the evening it is only tepid. We have been using the peak boost switch almost every day and have now got a large electricity bill.

could this be because the rod stat was not a gledhill and just a standard one? The new stat is set to max temp. Or does anyone have any other suggestions?

Also, if anyone knows of any experts in the sussex area contact details would be great.

Thanks
Hayley

Hi Hayley it mite b the rod stat that was replaced is not getting up to full temperature and cutting of before it's achieving that failing that check your header tank again and make
Sure u have enough water in it cause if not that could b a problem what part of Sussex u from ??

thanks for your reply. i will check the header unit again. why would the stat not get to full temperaturek? should it be changed againk? we are in haywards heath, west sussex. is that in your area?

It may b callabrated wrong so where it's supposed to cut of out say 70degrees it mite only b reaching say 60degrees which wouldent give u enough hot water maybe it needs
Changing again,,but let me no if there's water in header tank first vice versa the old stat got to hot hence why it overheated and u had steam everywhere and yes haywards Heath is not to far for me are u at bolnore ??

Yes in bolnore. I will check the header tank again tomorrow morning and the setting on the off peak stat. Thanks for your help, will be in contact again tomorrow.

So i have filled up the header tank a bit more and it seems ok so far. Going to give it a few days trial. Dazzaman - are you able to send your contact details if we need to call an engineer? Thanks for your help so far
