Boiler Controls

Using the boiler controls effectively is key to an efficiently working boiler. Learn more about them here.   Smart usage of these boiler controls can help you conserve energy and bring down that power bill. Your house will be comfortable in the right temperature and you can also avoid overheating your boiler.   Boiler Controls Built In Boiler Controls – these controls are useful if your boiler can be easily accessed, but not if your boiler is located in a garage or loft. On / Off Switch – Turning the switch on puts your boiler on standby until it is needed to make heat. Standby mode uses very minimal amount of electricity. Some switches feature selecting if you want to turn on both heating and hot water, or just one of the two. Temperature Controls – Some boiler models feature separate controls for the temperature of heat and hot water. Mechanical Boiler Timers – This timer can give you three options when you run your heating system: 1) the boiler is off, 2) the boiler is providing heat, and 3) the boiler turns on and off at set times. It has a large round dial that you can turn to set the correct time. The outer part of the dial has tabs that represent 15- minute periods that are selected when you want the boiler to turn on. A mechanical timer is simple to use, but it will set your boiler to turn on or off at the same time everyday. This might not work well if you have different daily schedules. Central Heating Controls – these controls are...

How To Calibrate A Thermostat

Want to learn how to calibrate a thermostat? We have outlined a few guidelines for you.   Your boiler thermostat can lose calibration after some time. This can come as a result of a number of different things like dirt or accidental bumping. Loss of calibration will affect the thermostat temperature, moving it slightly away from the correct room temperature. As a result, a room that reads 70 degrees might be read by that thermostat at 73 degrees, or too low at 67 degrees. A thermostat reading that’s too high can increase your energy bill by about 10 percent, and a reading that is too low will make the room feel cold even with the heater running. If your boiler is unnecessarily running more than it should, it is wasting energy and you are wasting money. This can be corrected through a simple solution: calibrating the thermostat. Even if you are not a professional engineer, you can learn how to calibrate a thermostat so that you can do it yourself. We have outlined a few simple steps for you.   How To Calibrate A Thermostat Learn how to calibrate a thermostat following these easy steps. Find out what type of thermostat you have. There are two types of thermostats: one contains magnetic contacts and a calibration screw, and the other employs a mercury switch. Clear the area. Clear the area around the thermostat. Check for things that might be interfering with your thermostat’s reading. A candle may be too close or there may be a cold draft from a window close to the thermostat. Check the thermostat temperature. Turn...

Central Heating Problems

RJ Gas Heating’s Registered Gas Safe engineers can fix your home’s central heating problems. We can service your home anywhere in East London. Our technicians are full trained and equipped to install and repair heating systems in homes and offices.   Central Heating Systems Using a central heating system simply means heating your home or office from one source. The boiler is the main part of your heating system. It heats water and distributes the hot water to other parts of your home: your kitchen, bathroom, and other heating units in your bedrooms or living room. A central heating system is an investment you would want to maximize. When used properly and with care, your heating system can help you feel more comfortable in your home. You can even lessen your power bills.   Types of Central Heating Systems There are two main types of central heating systems. A conventional boiler is the simplest to use and probably the most reliable. It includes two water tanks and a cylinder for heating. This means that water needs time to heat. A combination boiler, on the other hand, does not have tanks or a cylinder. It saves you a lot of space and there is no need to pre-heat the water, However, it can only support one to two water sources at a time and is not recommended for homes with several bathrooms or multiple users. There are also other alternate water heating systems such as those that are unvented. Common Central Heating Problems Here are some common central heating problems you may need to watch out for: 1 Boiler is...

boiler pressure too high

Boiler pressure too high? You can tell when the pressure gauge (see image) is generally above 2 or 2.5 bars on a gauge that looks something like the image here. Check your owner’s manual for the right amount to check if it is your boiler pressure too high. If you have bleed your radiators and the pressure keeps going up there are a few things that could be going on First, have you recently refilled the system and possibly left the valve on even the slightest bit? if all is okay there than it is likely that your expansion vessel may need re-pressurising or your boiler may have a split in the plate heat exchanger. Call us to let us help you with boiler pressure. If your boiler pressure too high beyond a safe point than a safety will cause your boiler to shut...

Boiler Pressure

If you your boiler pressure drops below 1.5 bars or below what your owner’s manual for your boiler recommends then you need to add water to refill your system. It is nature for  boiler pressure to decrease over time but if you are generally doing it more than once a year then you should call a gas engineer to find the problem. Below are some videos that cover how to add water to different types of systems to get correct boiler pressure. If boiler pressure too high then bleed your radiators.               Combination boilers or “combi” boilers have a feature that makes them stop working due to a too low drop in pressure. In most cases this is easily rectified and will take seconds. Pressure can be lost if you have recently bleed your radiators. If your system consistently loses pressure than you have a leak somewhere. This could be something as simple as a bleed valve that is not closed properly or a radiator valve that is leaking slightly, check all radiator pipes and valves for evidence of leaking. Leaks are normally very easy to spot as the water in the system is discoloured, if you find a leaking valve try to re-tighten it to stop the leak, otherwise replace the...

Summer Boiler Settings

Many modern boilers have summer boiler settings. If they don’t you may see just an image of a radiator with a plus or minus sign. You can turn towards plus in winter and towards minus in summer.. Some boilers may have different summer boiler settings which you can find in you manual. When the weather warms best to turn both both your thermostatic valves and your radiator setting lower. It can be a gradual process as spring moves into summer. You may want to check the temperature of your taps as well. Set it as low as you can get away with as in summer. Your bath doesn’t need the same temperature to heat up the water. For example you don’t need to heat up a cold steel bath in summer. If you are adding cold to a bath or to a tap in the kitchen you can probably turn down the temperature. This can save energy and water much of the time. Gas Heating is very cost effective generally but may not be if you don’t take care to maintain it properly so make sure you use your summer boiler...
