Boilermate II - No Hot Water.

Updated on February 4, 2014

Boilermate II

Your Boilermate II is now a few years old and you realise that it isn't as efficient as it first was. In fact it is showing definite signs of old age and you wonder if it is time to replace it. It may be that it is costing you money in repairs.

Don't despair, it can be fixed in most cases, but parts are getting quite scarce.

Is the temperature of hot water from your taps getting cooler and may even be non existent. Does your central heating work though ?

Chances are it will be the 'Oventrop' mixer valve which comes fitted to your Boilermate II which is failing and needs to be replaced.

This is an easy fix and can be done for reasonable cost.

No hot water.

This always happens when the weather is coldest or at a time of year when to call out an engineer just isn't possible.

Don't worry, with the help of this guide, e-bay and a bit of D.I.Y knowledge your hot water will be restored quickly and cheaply.

To restore your hot water to optimum temperature is not as hard as you may think. No hot water will be a thing of the past. Above all you will be happy in the knowledge that you attempted it yourself.

I know because all the repairs on my Boilermate II have been done by ME.

What problems does your Boilermate suffer with ?

Your Boilermate II is old.

No problem. My Boilermate II is 15 years old and still going strong along with the original boiler. Yes there have been problems, but, nothing I have not been able to handle. Over those years I have watched neighbours pay £1000's in repairs as well as replacement systems. Not me and the same will be for you.

Take your time is my advice to get the diagnosis right so you don't waste money in buying parts that you don't need.

Tools you will need.

  • Adjustable wrench
  • Spanners
  • Jointing compound

So you have no hot water.

Over a period of time my hot water temperature went from scalding hot to non existent. It was all because the Brawa Mixer Valve connected to the system had disintegrated inside the body and wasn't mixing hot and cold.

I bought a hardly used item on e-bay for less than £70 and it cured the problem first time.

Inside the body when I removed it was a mass of broken plastic which was blocking the hot water coming in.

As soon as I replaced it the system was restored back to normal.

Replacing your Mixer valve.

Follow the guide and you won't go wrong.

#1 Turn off your water supply at the stop tap and Boilermate system at the electricity supply.

#2 Drain any water left in your taps.

#3 Undo the nuts on your faulty mixer and carefully remove without damaging pipes around it.

#4 Cover threads on your replacement mixer with joining compound and fix in place.

#5 Tighten all nuts back up.

#6 Turn water supply back on and electricity.

#7 Check for any leaks.


Setting the correct temperature.

Once you are happy with the fact that you now have hot water again you may find that your water temperature needs turning up or down.

On the top of your mixer valve you will see a green or white adjustment knob. To set the temperature all you need to do is turn the knob up or down by 1/4 of a turn at a time until the required safe temperature is obtained.

    Hi Paul, yes you are quite right. Setting the water temperature can be done by turning the knob at the top only 1/4 turn at a time. Small adjustments are needed to get the right setting for you. Once a safe temperature is obtained you shouldn't need to alter it as the summer / winter settings on the Boilermate II will take care of this.

    Hi Steve, very helpful article. thankyou. just one question - once you have reinstalled the valve do you have to "set" the green knob on top of the valve, and if so, how would you do this? Is it common sense? :) thanks again. Paul.

    Tirelesstraveler, the boilermate is the storage tank for your hot water made by the boiler which makes instant hot water.

    Is a boilermate the same as a water heater?
