Boilermate II problems

[mikepmk]

We have a Boilermate II FE200 fed from a new Worcester Bosch boiler.
Pumps are new.

We can get hot water but not heating.

Whilst the pipe from the boiler to the boilermate is hot , the pipe back out to the boiler is cool, the pipe leading to the central heating pump gets hot only if CH is off for an hour. When CH cuts in, hot water flows for a couple of mins then cools down.

Had 3 heating engineers round, their best guess is that the problem is caused by scale and the soultion is to replace the Boilermate.

Q1. Is there another explanation for the problem?
Q2. If it is scale, can it be de-scaled ?

If the DHW is working then the cylinder is being heated up. It looks as if your CH circuit is either blocked or air-locked.

If it is a scale problem they can be descaled. No need to run and buy a new one. If it needs descaling it has been neglected. I would have the CH circuit cleaned as well. Install a Magnaclean filter on the CH circuit return pipe. Make sure about 4 1 litre cans of inhibitor are in the system.

BoilerMates are great, However they need the inhibitor replacing every 4 years and 4 cans of the stuff in the average house. The Magnaclean filter will help a lot.

Cowboys tend to condemn these (they tend not to understand them) and sell unvented cylinder and big bucks when all they need is the system cleaning and Boilermate descaling.

Thanks for this.

How do we get the boilermate descaled? How do we find someone who shares your view that "throw away and spend thousands" isn't the only solution?

There are companies that specialise in cleaning and descaling. On of the contributor on this forum was into it.

BoilerMates are great,

Cowboys tend to condemn these (they tend not to understand them)

and those that do don't fit them salesman

Very true. Many who do not fit them don't understand them.
