The combined boiler was invented many years ago and is designed for properties without lofts as well as apartments and apartments. We all know that there is limited space in apartments and apartments. Then, when he appeared on the market, he was hailed as a revolution.
It is described as a clever boiler (gas boiler repair) that saves on small homes, central heating and hot water, all from small built-in boilers, eliminating the need for hot and cold water tanks and continuous hot water on request.
Today, combined boilers account for around 50% of all boilers in the UK. These new, unprocessed boilers now produce more hot water than before, and are very efficient, thus reducing energy costs. If there is no maintenance, the combined boiler often encounters some problems, which are hot water problems and pressure problems. The first problem is with hot water, you may notice that the water is not as hot as it is usually, and sometimes it may get hot and cold again. He can only warm Luke.
If you open the hot water tap near the boiler, check it out and see what happens. You may notice that the temperature rises rapidly and the boiler is turned off; then, after about 20 seconds, the boiler is turned back on. This is one of the most common problems with boilers, which means the boiler is overheated.
When hot water is required, the internal bypass valve changes when the boiler circulates, so that the water is only heated in the boiler, not through the central heating. Pump the water through the hot plate heat exchanger. In principle, it works in the same way that the bottle is placed in a pan with warm water, and the temperature of the bottle is the same as that of the pan.
These two waters never touch each other. The water circulating in the boiler is not the water flowing out of the hot water tap. The reason why the hot water deteriorates with time is because the internal blockage of the hot plate heat exchanger is small, the water in the boiler cannot pass quickly to heat it and the boiler starts to overheat and stop, and finally the hot water will stop working.
So how do you avoid these problems?
When installing a new boiler, clean and flush the entire system. The reason for cleaning is to remove waste and sludge from the system. Mud is the biggest problem, it causes more failures in the boiler than anything else. Once the system is clean, an inhibitor is added to protect the system and prevent sludge build-up.
If you have a hybrid boiler a few years ago you have noticed that the hot water is not as hot as before, you have to check the mud accumulation of the boiler and system. If your boiler is gas, be sure to only ask the gas technician. Another common problem with boiler combinations is due to the expansion of the container. You may notice an increase in the pressure gauge and then release the water through the pressure relief tube. Any boiler that heats water and central heating should provide annual service.
Part of this service is to make sure everything is safe and the boiler is running. From a conceptual point of view, the analyzer must be used to check the combustion and adjust if necessary. The expansion tank must be inspected and restored if necessary, which often loses service, but it is a very important part of the boiler (gas boiler repair). If not checked, the pressure will decrease and you will notice an increase in pressure and then drop to zero. The inhibitor in the system must then be recharged if necessary, doubled and not protected. Once this happens, the mud will begin to form, so this is very important.
