Gas Fire Service

If you have a gas fire an annual service is extremely


Gas fires are an open flued appliance, which means

they take their air from the room they are in. This

means if they give off carbon monoxide, it will be in

the same room as the fire, which is the exact same

room that you or your family are sitting in!

A number of things can contribute to carbon

monoxide being present such as insufficient oxygen

due to lack of or no ventilation, debris on the burner,

a partially blocked chimney, etc, etc, etc.

There are some tell tale signs that some of these

things may be present such as soot build up or

staining on or near to the appliance and all this can

be remedied with a simple service.


It's no fun when in the depths of winter you find you're still cold and looking for a jumper long after switching the heating on!

This is when your first call should be to Gas Man Den to arrange a speedy response, whether it's in the middle of the day, before you leave for work, or in the evening when you get home.

Then after a quick diagnosis and fast sourcing of parts a repair can be carried out to get your home and hot water nice and warm again.

Landlords Gas Safety Inspection.

CP12 landlords Gas Safe certificate.

If you have a property you rent out, or if you have people living with you that pay you rent, you are classed as a landlord and must have an up to date landlords gas safety certificate.

These are to to carried out annually & are a legal requirement.


Just some of the reasons to have an annual boiler service for are:

1. To check your boiler gas pressures are correct and your not throwing money down the drain by having them set too high.

2. Carrying out a gas tightness test to check for gas leaks, which can be tiny and if in well ventilated areas never smelt, which again is a waste of money, not to mention dangerous

3. Checking the boilers case seals are intact and inspecting the flue for signs of deterioration, or poor installation, so that no poisonous gases can escape into your home.

4. Checking for signs of parts starting to malfunction or leaks starting to appear and stopping them before they cause you more expense later on.

5. Possibly one of the most important things is to analyse the flue gases, to make sure there are no dangerous levels of the invisible, odorless and tasteless killer carbon monoxide.


Gas Man Den provides a fast response for all your boiler and plumbing problems. Followed with a quick diagnosis and sourcing of parts at reasonable prices, so as to get you up & running again as soon as possible.

Dennis at Gas Man Den has worked on over fifteen jobs large and small over six or seven years at our house and has never let us down. Jobs included stripping down a hot water and heating system, replacing a boiler, installing a water softener, performing gas safety checks and even fixing a pump in our pond and rescuing our fish. He also managed to sort out a friend’s ongoing boiler nightmare on Christmas Eve a year or so ago when others from larger companies had failed so that they and their children including a very young baby could remain in their home for Christmas. He is responsive, responsible and reasonably priced. We always know where we stand with him and cannot recommend him highly enough.”

M-J Islington, london.

We recently had a new combi boiler fitted by Gas Man Den and it has transformed our lives! We had been considering a new boiler as our old one was worn out and our fuel bills were sky high. We had a quote from British Gas which put us off as the price was so high. I looked up the Gas Safe registered plumbers in our area and had several quotes. Dennis stood out because he was prompt, enthusiastic and creative in his solutions for our hot water and heating needs. We originally had the boiler upstairs in a bedroom and hot cold water tanks took up most of another cupboard on the same level. Cold water pressure was poor and hot water took ages to come through. The noise from the system kept us awake at night! Dennis found space in the kitchen for the new boiler and we now have mains pressure hot and cold throughout. It is quiet, efficient and fully guaranteed. We also had loads more storage upstairs! What more can we say – Dennis is a miracle worker and we would recommend him to anyone.
