Question about Heating & Cooling

2 Answers

Can you explain how big a room needs to be for an outset gas fire? We have no flue or chimney of any sort, but due to regular power cuts during the winter we need a gas fire as our central heating is powered by electric but we can't find any info anywhere about what's needed for these types of fires

Hi,
All of the new gas fireplaces have oxygen sensers on them that will cut them off if they deplete the oxygen in the room...
No matter how big the room is you wan to make sure that you crack a window open when running the fire...this will keep enough O2 in the room....
I always reccomend getting a digital read out CO (carbon monoxide) detector also... this will protect you in case something happens and the flame goes bad and starts to give off the unseen and odorless CO that will just put you to sleep...forever...

Have you seen this video on Vent free gas heaters and why they are safe?

    A free standing vent free heater does NOT need power to work. The thermocouple does all the work. They are nice to have as backup heat when no power is available. Comes in Nat gas models or LP models needs no power to operate.

Even if it was a wood burning fireplace from the beginning & was converted to gas ?


Now that's a LOT of additional information. I hesitated to answer your question the way it was worded originally.... IF in fact it is a masonry chimney and originally built to burn wood, you should have a chimney sweep do a thorough inspection of the flue to ensure it is safe to use again. Flue temperatures, while burning wood, EASILY exceed 1200 degrees whereas natural gas flue temps are in the 450 degree range.

It also should have a clay tile liner and not be fabricated of brick only. The unsafe thing of an unlined brick chimney or a chimney with a severely cracked liner has to do with unburned gases condensing within the inner surfaces of the chimney. Some of those gases are moist and will condense on the inner surface and eventually have an unsafe build up that can be ignited by an oversized flame or excessive sparks causing a flue fire. During a flu fire, temperatures exced 2000 degrees and an unlined BRICK flue of that age could have lost some mortar allowing superheated gasses to seep into the crevices. Those superheated gasses then explode when igniged by the flue fire and either do extreme damage to the flue, blow the entire chimney apart or in the worst case scenario burn your house down.

I'm sure you've seen houses burnt and the chimney was left standing....but you have also seen damaged houses with the chimneys blown off the end of the house and laying in rubble toppled out into the yard. The latter visual picture was an example of the end result of the gasses exploding. If the chimney was inside the house instead of on the end of the house, the house would have been burnt also.

There is a lot to be careful about when heating with wood and to start off safely you need to have your chimney inspected and the gas components removed with the gas line capped EXTERNAL of the fireplace.

I can hear the wind blowing extremely noisy from my gas fire /chimney


It is not likely blowing from the fireplace, rather your hearing outside wind noise through the chimney pipe.
On windy days this is normal.
The noise can only be limited by the flue pipe damper and the length of the pipe.

Sirocco eco 3 gas fire. Flames burning ignition cable


Yellow flames is lack of air blocked burner ,blocked injector , low gas pressure .

I would put a smoke pellet up the chimney to see if you have a pull on the chimney to see if it is not blocked , or if you have down draught what sort of pot are you thinking of putting on the top ?

When the hot water heater is running water leaks from the chimney. the pipe from the heater to the chimney is dry upon removal. about 3 gals. of water leaks from the chimney with two showers.


If I understand correctly, your Bock gas water heater vent is causing water to leak down into chimney.
This is a very serious concern

Water leaking from water heater flue indicates improper venting.
The hot air gasses from water heater combustion contain water vapor, but the gas should vent out of house before condensate forms on pipes.
http://waterheatertimer.org/Water-at-bottom-of-water-heater.html#flue

The problem might be caused by a power vented furnace that pushes vent air from furnace down into flue pipe for water heater. As a result, the water heater doesn't vent properly.
There could also be a clog.
Light a match under water heater draft hood and see if smoke from match travels instantly upward.

There are two major concerns.
1) If vent is not working, it means that odorless CO gas is entering home instead of venting outdoors.
CO carbon monoxide is deadly poison.
http://en.wikipedia.org/wiki/CO_poisoning
This is a very serious concern
You can buy CO detector after vent is repaired.

2) Water condensate will eventually rust away vent pipes because of acidic content of the combustion vapor. It can be expensive to replace pipes, and pipes with holes pose risk of CO poisoning.

My suggestion is call a qualified plumber ASAP and explain what you observe.
Plumber will want to inspect the vent pipes, and may want to extend water heater vent pipe up further inside chimney so furnace is not pushing air back into water heater vent.
Plumber may also find blockage somewhere in the vent stack or chimney.
Also post on a professional water heater forum like the Tank to double check anything the plumber says to you. These are the pros.

I have a quebb master multi fuel fire/stove it has a top flue pipe fitted how can i gain access to the flue to enable chimney sweeping


Hi Davebingj, It is quit simple to solve this problem. Inside your Quebb is a removable roof. You can lift up the roof a small bit, fold it together and pull it out of the front door. Then you have full acces to the flue pipe at the end of the stove. With the sweeping gear, which can bent easily, you can sweep the chimney very good because the sod coming out is staying inside the stove and doesn't sweep aroun the room. Hope this will help. If not give me an mail at: marbert2@eircom.net Hubert.

Hello, I'm having problems getting a new gas fire fitted in my rental property. I have been quoted at £763. I already have a coal effect gas fire on the wall (no fire place) with a flue and obviously...


Older fires have an exhaust flue and get their air supply from the well ventilated room in which they're fitted. Balanced flue fires are the correct choice for rooms which lack sufficient fresh air ventilation. They have a flue which draws in outside air necessary for combustion whilst also acting as an exhaust for the combustion products. To work the appliance must be completely sealed so that no air is drawn from the room; the pressure of the incoming air and the pressure of the outgoing exhaust is equal so the flue is described as balanced.

The lack of a requirement for fresh air ventilation means that less energy is used; open outside vents let heat out as whilst allowing fresh air to enter.

Balanced flue appliances which exit directly through an exterior wall should cost very little more to fit than a regular appliance: the only additional cost may be in blocking up the old flue outlet and creating a new one but this rarely takes more than half an hour. A sealing collar is fitted to the outside of the flue (included in the flue kit) so there may be additional costs in hiring a ladder (or even erecting scaffolding) if you're higher than the ground floor.

Budget-level balanced flue fires typically cost between £350-£500 and the fitting charge may be fair depending upon your property, but it's also worryingly vague. A properly qualified and experienced gas fitter should be able to give you a precise quote and will already possess all of the tools needed to fit a new flue.

Also, ensure that you have your landlord's written permission to fit the new fire. If you don't then the landlord can claim that you have damaged the property and demand that you restore the property to original condition when you leave. If you get permission then you can also expect your landlord to insist that when you leave the property you do not take the new fire with you and that you supply an original copy of the gas fitter's installation certificate. Without this the landlord is within his/her rights to commission a safety inspection at your expense. Note that subsequent annual gas safety checks are required to be carried out by the landlord at his/her expense as per normal.

Hi,

You will need to install a flue liner ( i know its a nuisance) to allow the products of combustion to escape as quickly and as safely as possible.

If you installed a gas appliance without a liner, due to the temperature of the flue gases (lower than solid fuel) the emissions would struggle to exit via the flue terminal.

If you install the appliance following the manufacturers instructions, you cannot go wrong. The other recommendation is get a 'Gas Safe' engineer to carry out the commssioning/testing.(house insurance void if not certified)

I hope this helps.
