A central heating pump is a very valuable appliance in any house especially during the colder months of the year. It is just impossible for one to imagine having to go without centralized heating in the middle of November. We use our central heat pumps 24/7 during the winter months but this can lead to a lot of problems. Overworking a centralized heating pump will result in a lot of kinks along the way. However, troubleshooting those problems does not have to be really complicated. Some central heating pump issues are simple enough for an average homeowner to fix on one’s own.
Step 1 - Diagnose the Problem
There are a couple of tell-signs that will alert a homeowner that the central heat pump is encountering a problem. The most usual kink that a person will encounter with his heat pump is the failure to heat properly. This may be an indication of a bigger problem. Try relighting your pump’s pilot light. There are different methods of relighting a pilot light. Refer to your heat pump’s user manual for the instructions. If the problem is not reversed with that step, then something else is causing the malfunction.
Step 2 - Solve the Leaks
The next possible culprit to your heat pump problem is a leak in the pipe. In order for you to verify that a leaky pipe is definitely the problem, you need to look for water patches on the floor. Patches will be more evident on your house’s ceiling and second story flooring than on the ground floor. If you can’t find any, take a look at the combi-boiler of your pump. A drop in the pressure reflected will indicate that there is indeed a leak.
Inspect the pipes for leaks. Turn off the central heating system before you start working. If the source of the leak is a joint, tighten the joint with the use of an adjustable spanner or wrench. Wrap tissue around the joint and wipe it dry. If the leak is a product of cracks and holes, drain the entire system first before you replace the section of the pipe with a new one.
Step 3 - Check Radiator Problems
A radiator problem is often indicated by a heat pump system that is working properly but it has a cool radiator. In order for you to verify that your radiator is indeed the problem, you need to check the thermostatic valve of your pump. Make sure that the valve is opened just enough to let water through. If you find an inconsistency with the thermostatic valve, go to the lock shield valve. Make sure that the lock shield valve is open. If not, use a spanner to make the necessary changes on the valve. You will have to bleed your radiator next. Turn of your heat pump for a few hours and place a cup or bucket under your pump. Bleeding your radiator will require the use of a key. You can get the key from your heating shop. With the use of the key, open the valve just enough for the air inside to escape out.
