Domestic oil fired central heating. Keeps tripping out with no oil feed(has tiger loop and this is empty) If oil is drawn through filling tiger loop again boiler will fire up and run for betweeen 2 days and 3 weeks then same again. Was told that 10mm feed pipe was to large so changed to 8mm but has tripped out again, have checked all connections and all seem to be airtightTank is top outlet bunded and boiler is 50/70 eurocal. and about 4 to 5 metre total pipe run from tank out let to boiler inlet. Tank stands at same level as boiler. Can anyone help Thanks

Many times the feeder tube from the bottom of the tank becomes perforated. the return tube is ok most of the time . try switching the 3 8 tubes from inlet to outlet and see if problem resolved. if so the the tube down into the tank is flawed.

How do I fix central heating


The first thing you need to substantiate is the fact that there is enough water in the system. It will be a closed loop system requiring approximately 10 psi/ floor. (Only a rule of thumb). Usually when one protion of the system works and the other does not, it is an issue of water quantity available to circulate through the combination of loops. If you have to add water, you will probably have to purge air from the highest points in the system. Even if there is an "Airtrol" fitted in the bottom of the expansion tank, bleeding the high points will eliminate air quicker.

The hot water portion of the loop should only be going through a heat exchanger that transfers the loop temp to the domestic water circuit and the three way valve is probably a 'mixing valve' utilized to maintain a certain loop temperature on the primary loop.

Ravenheat 80/20 boiler. the boiler looses water pressure but only when working in central heating mode. Boiler holds pressure indefinitely if central heating is not used,hot water can be drawn without a...


Hi, your boilers pressure should be holding 1.5 bar with the relief set about 3. If the pressure is below this the flow switch will cause the boiler to stop as theirs not enough pressure to operate. Another thing, does your boiler have an auto fill system or do you need to plug a hose in to fill it? If its an auto fill system and you lose pressure you could have a leak.

Symptoms sound like crossover might be part of problem:
Crossover is when cold water enters hot water line due to faulty plumbing part like check valve, mixing valve, or bad faucet cartridge.

Step one; did you replace the old thermstat with a manufacturers original thermostat?
Off the shelf thermostats do not have the same settings as an original manufacturers thermostat.
Step two; Did you replace the thermostat in exactly the same place and way as the original? This is important.
Finally there is no feed back loop? this is a typical comment from an engineer. Domestic fridges are built to a price and luxuries like feed bck loops are not deemed necessary

try bleeding the radiators in the order of downstairs first and then the upstairs and try to bleed them in the order they fill, trapped air can take a while to escape, a good sign on a radiator is the bottoms being warm where the tops( where the air is trapped) stays cooler, a sure sign to which radiator needs bleedin, hope this helps, colin

Oil fired boiler 2 pipe system 150ft to tank


Hi,
A two stage pump may help, because you are pulling a long distance. However I have found that a little contraption called a "Tiger Loop" is much more effective at making the problem you are having go away.
I have written a tip here on Fixya that you can see by going here

http://www.fixya.com/support/r3571544-oil_burner_problems_can_sometimes_be_fix

This unit will cut the amount of oil that you need to move through only 1 of the pipes down to amount that is actually being burned.
Be sure to use the "supply" pipe to hook to the Tiger Loop.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

Vaillant Ecotec combi boiler - radiators working but no hot water flow to taps


David,

The fact that you're getting a little burst of domestic hot water suggests that the boiler is capable of circulating hot primary loop water through the heat exchanger, but doesn't necessarily do so when it needs to.

What seems to be lacking is a recognition that domestic hot water is now being drawn off, and that the boiler needs to fire up and divert the primary flow through the heat exchanger.

A good place to start might be the flow switch (usually in the bottom of the boiler, where the cold water supply comes in) or the electrical connections to it.

My Central heating wont come on. There doesnt seem to be any lights on the boiler/burner. Why could this be. First time I've tried to turn it on this season...it was fine back in february. Thanks!


Is the switch off?

Check the fuse panel/breaker box.

Is the thermostat switch set to heat?

Is system oil heat? If so check the following...

Some systems that use oil have an emergency switch (sometimes with a red plate) located away from the unit usually the basement staircase.

The oil systems also have a heat element above the burner on ceiling that "trips" if there is excessive heat. This shuts everything down so as not to feed a possible fire with oil.

Check the gun (burner itself) and try and locate a little red reset switch located near the back side of gun. Try pushing it in to see if its tripped.

If these quick checks don't help then it would be wise to call a technician to check your system for issues. Heating systems are too critical to "play" with and problems are best left to the pros for safety's sake. Good luck, I hope this helps.
