Warm but not Hot

Post  wwtsc00 on Thu Sep 19, 2013 3:08 am

Hi
My Mum has just taken over a McCarthy & Stone apartment which has an A Class boiler in it. The water is only mildly warm and I have never come across this system before.
Both the hot water and Off Peak switches are on, the green boiler light is on constantly and I have topped up the header tank. I only switched on 2 nights ago so does it take time to build up the heat, or will I find an external timer or thermostat somewhere?
Thanks for any help
Terry

What to do with your Pulsacoil A Class

Post  sunny.sahdev on Thu Sep 19, 2013 4:08 am

Hi Terry,

The timer should be positioned near the unit. If you can not see one, check in case you have a eco 7 supply. You should see a black button near the LED on the top right hand side of your panel, press and hold that button for 2 seconds, it should light up. Once it lights up, wait about 5 hours and you should have hot water (this is the manual boost). The bottom element if it is receiving a supply may be faulty or the contactors have burnt out which is a common problem. You may need an engineer to look at the system.

Before you call anyone out, I would strongly recommend you have a read of the Self Check Pulsacoil Guide which you can find via this link: Pulsacoil A Class

This should help a little.

Regards
Sunny

Hi Sunny

Thanks for the reply. I have tried what you suggest and confirm that the booster is working fine. There is no timer as it is on Eco 7. I assume then that there is no timer or thermostat anywhere that needs tuning. So from what you say it must be the bottom element or contractors. I have never looked inside one of these, will it be obvious what I am looking at when I remove the cover? I am an electrician by trade so feel confident in having a go, or do you think it better to get an engineer.

Regards
Terry

Hi Terry,

I would always recommend you call someone with experience, if you would like you can call us on 0800 046 1241 and we can arrange for an engineer for you. I would also recommend you check internal components for signs of burning, specifically the contactors.

I hope this helps
