Hi can anybody help,i have a vaillant combi boiler and i cannot turn the heating off on the radiators can anbody help cheers!


If you they won't go off when your timer is off. There's a possibility it's clock keeping it on although its turned off, which is fairly rare. However depending in which model of Vaillant you have, if your boiler has a hot water pre-heat on it. Some models which have this the diverter was prone for sticking thus leaving the port for the radiators open when in hot water mode.

Your pressure relief valve is probably bad, replace it. You might want to tap on the expansion tank to see if that is empty. If it is full, replace it.

Is it safe to run a Vaillant Turbomax Plus with the water gauge in red?


No, look for a small diameter pipe (1/2") supplying city water to the heater. On that pipe there should be a shut-off (make sure it is open), a back flow preventer (looks like a brass can with ribs) and a feed valve (looks like an upside down Ice Cream cone with a brass tab for a tai). Lift up on the brass tab to allow water to the boiler till the dial indicates Green. Sounds like this will need to be adjusted to keep the pressure in the boiler to manufacturers specifications.

Clock on comi boiler


it may be the preheat setting on the boiler for the hot water circuit. do the radiators get hot when the boiler fires up with the time clock off ? if not then there is nothing to worry about if it is only on for a short time.

Hi,i have a vaillant turbomax combi boiler,the radiator side is working well but when running hot tap the boiler kicks in for about 5 seconds ,hot water starts to flow then boiler cuts out,water runs cold...


Which turbomax, as there a two different models. The more modern one, with the brass CPL diverter valve, located at the front left of the boiler, was very prone sticking & jamming, this would restrict flow through the hot water circuit in the boiler, and cause cycling. Vaillant actually modified the diverter. You can identify, if it is the old type, as there is a very small hole in the middle of the diverter on the old ones, probable no more than 1mm-2mm wide. The modfied one, is much bigger approx 5mm wide. If old type, replace as this usally sorts the problem

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.

I have a multifuel stove which runs my central heating system from its back boiler. When it gets really hot there is a loud clicking and knocking sound from the rear of the stove where the thermostatic...


That clicking and knocking noise you hear is called cavitation. It's when the bubbles of steam are cooled down rapidly and implode upon themselves. Cavitation is not a good thing to have in a boiler as it can cause dramas. This cavitation is more than likely because the boiler is firing too hot. A service technician should be called to turn the regulator down a little bit.
