Find a Heating Engineer you can trust in Hemel Hempstead.

The size of boiler you need will depend on the size of your home, how many radiators and bathrooms you have and how many people live there. The boiler size refers to its output, which is measured in kilowatts (kW), rather than the actual dimensions. Speak to your boiler engineer about which boiler is suitable for you, as if you have more than one bathroom or a lot of people in your home a combi boiler might not suit you. Other boiler types such as system boilers or conventional boilers may be better suited to larger homes because they have bigger outputs.

A combination boiler, also referred to as a “combi boiler, delivers both domestic hot water and space heating in a single package so as to save space, and in a lot of cases, money. These great features makes the appliance a very popular choice in UK homes and in fact, it represents more than 50 percent of all new boilers fitted in the UK on a yearly basis.

Most modern and high efficiency combi boilers are usually stainless steel condensing boilers which normally features an in-built secondary heat exchanger to deliver domestic hot water to a home or property. What’s more? When it comes to the heating season or the cold months, the combi boiler will operated as required to heat a structure and offer hot water for showers, sinks as well as other hot water appliances around the house. And when it gets to the warm season or summer months, the combi boiler will only work when there’s a need for domestic hot water which also helps you save more money.

Combi boilers are able to provide domestic hot water in such a way that’s energy efficient due to two primary reasons - the combi units possess a very high operating efficiency and also have a low internal water volume. As a result, in during the hot summer when space heating is not required, you’ll only have to pay to heat up the hot water that you really need and not an entire tank.

Combi boilers also have the following benefits:

✓ Lower costs. Due to the combined nature of the boiler and the lack of tank in the roof space, the installation time and costs are at a minimum.

✓ Saves space in your home as it effectively combines a central heating boiler with a water heater into one unit.

A boiler is simply the most important part of a central heating system as it generates the heat that warms up the home or property. Basically, the appliance or small furnace makes use of gas, LPG or oil in order to fuel its operation. However in the UK, most boilers are usually fuelled by natural gas which is supplied automatically from the national gas grid. And depending on how it operates, there are various types of boilers.

Typically, a gas central heating boiler will have multiple pipes entering from underneath. While one pipe supplies the boiler with gas from the mains gas supply, another pipe allows cold water to enter the boiler to be heated, the last pipe then enables hot water to exit the boiler so it can be distributed around the home.

✓ There are fuel jets and heat exchangers inside the boiler. When the heating is turned on, a valve is opened to allow the mains supply gas to enter a sealed combustion chamber in the boiler. There are multiple little valves which permit the entry of the gas before being ignited by an electric ignition switch. These jets heat a metal component in the boiler known as a heat exchanger which works to transfer the heat to the cold water pipe and heat up the water.

✓ Once the water has been heated to the target temperature, it’s then pumped through a circuit of pipe which runs around your home by an electric pump.

✓ The heated water enter each radiator, is then transmitted via a closed loop and radiates heat into each room.

✓ Once done travelling through all radiators, the water then returns to the boiler at which it must have been cooled. Therefore, the boiler will have to reheat following the same process before circulating. The water can only be drained by a professional Gas Safe engineer

How Long Does It Take To Service An Oil Boiler?

Are you about to service your oil boiler and wondering just how long it would take to completion? Well, you should first know that during an oil boiler service, there are a wide range of things that needs to be checked. As a result, the service can actually take some time and even more, depending on the present condition of your oil boiler.

During a boiler service, your qualified heating engineer will carry out the following tasks:

• Detach and clean both the burner and fan.

• Examine the combustion chamber rope seal.

• Wipe clean and descale baffles.

• Wipe clean and descale the main heat exchanger

• Detach, clean and replace turbulators

• Examine the combustion levels after cleaning.

He’ll also perform some tank and system checks which includes:

• Inspecting and cleaning condensate

• Testing the fire valve

• Cleaning or replacing the filter

• Cleaning the condense trap

• Conducting a thorough inspection of the tank and oil supply pipe to identify possible damages, deterioration as well as debris.

• Pressure testing the oil supply pipe at the point where it goes underground.

• Examining the system pressure.

With all the aforementioned activities and more, an oil boiler service may take relatively longer period of time when compared to it’s counterpart - gas boiler. This is mainly due to the fact that the boiler itself requires a thorough inspection as well as the oil tank where the fuel is being stored. You get your gas through the mains supply, however oil must firstly be stored inside the tank then filled up when it’s almost low. The oil tank will be inspected to identify possible leaks, bulging, corrosion as well as water.

So generally, an oil boiler service should take between the range of 1 to 2 hours to be completed.

What Is A Gas Safety Certificate?

Do you wish to know what a Gas Safety Certificate is and if you need to get one?

If you’re in the UK and you own a rental property, you have a statutory obligation to obtain a Gas Safety Certificate. The law ( Gas Safety - Installation and Use, Regulations 1998) stipulates that landlords as a matter of necessity should have all their gas appliances, fittings,and property flues subjected to yearly checks in order to ensure that they’re are totally safe.

The Gas Safety Certificate can be referred to in a number of ways which includes Landlord Gas Safety Record ( LGSR) or CORGI PROFORMA 12 (CP12). The later dating back to when the official body for gas safety in the UK was CORGI. However, the official body is now known as Gas Safe, hence it’s now usually called a Gas Safety Certificate or something along that line. But regardless of whatever you choose to call it, as long as you reside in the UK, it’s crucial to know that if you need one as soon as possible. So how do know if you need a Gas Safety Certificate?

If you’re a homeowner with a property that you live in, you’re not required by the law to obtain a Gas Safety Certificate. There’s nothing like a homeowner’s gas safety certificate, however we’d recommend you subject all you gas appliances and pipework to yearly examinations to ensure they’re functioning properly and safely.

If you’re a landlord in the UK, you’re required by the law to get a Gas Safety Certificate to ensure your property is safe for your tenants. You must reach out to an approved Gas Safe engineer who’ll carry out annual checks on your appliances to ensure that they’re totally safe.

Biomass boilers can be designed to work with other kinds of heating. The most common of these is solar thermal. This is a popular renewable energy pairing. Solar thermal heating will meet your hot water needs during the summer while a biomass boiler can operate as a backup during the winter when solar thermal panels do not perform as well.

How To Fix A Broken Boiler

To fix any problem when it comes to home appliances, the first step is always to identify the problem while also carrying out thorough checks - a broken boiler is not an exception.

To do this, you simply have to follow the detailed instructions on your boiler’s manual strictly. If after following these actions to the letter and the issue remains the same, then you’d probably need the services of an a qualified engineer. Never try to fix the issue on your own.

✓ Check the pressure. The solution to the headaches might sometimes be as simple as examining your appliance’s pressure gauge. Here, the good numbers are around 1.0 or1.5, if it happens to fall below this, then you should open the boiler’s instruction manual. You can also inspect your radiator valves for any leaks. You’d have to call in a specialist to solve the issue.

✓ Check the thermostat. Here, it’s important to note that a faulty thermostat doesn’t necessarily imply a broken boiler. It may just signify that you need to replace your thermostat. Simply check to ensure that your thermostat is turned on and temperature is at the appropriate degree.

Can You Get Oiled Fired Combi Boilers?

Absolutely! Oil fired combi boilers are not only a super cool alternative to gas heating, but also offer a cost-efficient means of heating your home. And this is best enjoyed especially if you’re one of the estimated 4 million houses that are not connected to the gas network.

Oil fired combi boiler enables you store fuel close to your property and fill it as required. There many A rated model options available in the market with the modern oil fired combi boilers confirmed to be up to 95% efficient.
