The best time for a boiler service is in the summer when you’d probably would not really need the system, so you can take advantage of that as well as the possible lower boiler servicing cost during this period.

Before we look into the amount of time a boiler service should take, let’s first consider what should be done during a boiler service.

✓ Visual inspection. This is a check carried out by the heating engineer to ensure your boiler still meet the existing standards and requirements while also looking for any faults.

✓ Removal of boiler casing. There’s the need to ensure everything is working just fine and also to clean the boiler’s interior. These inspections should include the burner, heat exchanger, main injector and spark probe.

✓ Flue check. This involves making sure that there’s no form of obstructions in the flue terminals as also to ensure that the flue is well installed.

✓ Gas pressure check. This involves making sure that the boiler working with the appropriate pressure.

✓ Boiler fired up. This involves checking for any operating issues.

Generally, a boiler service should be completed within 30 minutes, however this time may vary largely depending on the brand and model.

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.

Smart controls such as Hive are the next generation technology with more and more people now converting their houses into smart homes to control multiple devices in the homes remotely. Smart technology can be incorporated with several household devices such as security, lighting, entertainment and more. But what if there’s an oil boiler installed in your home, can you still connect your Hive with the your heating? Well, simply read on to find out.

The answer to this question is yes, most oil boilers are compatible with Hive and can substitute for either an existing conventional programmer or thermostat. The smart technology works to help derive more benefits from your heating system and they usually come with apps which can be used to control your home’s heating from anywhere with just your mobile device. Hive, however, cannot work to replace the functions of smart oil boiler heating controls to modulate your heating as they only work on an on or off basis. To make use of the modulating technology in an oil boiler, the cost of manufacture would be considerably higher while offering little advantage in efficiency for the home or property owner. Ultimately, this implies that you can’t incorporate smart technology to control the output in a similar way as a gas boiler, but there are still some ways to utilize smart technology with your oil boiler in such a way to boost your efficiency and lessen the energy bills.

Do you want to use your Hive with your home’s oil boiler? We’d advise you get in touch with an OFTEC qualified engineer if you wish to install Hive Active Heating on your oil boiler, as British Gas engineer do not offer this service.

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.
