Heating Engineer FAQs

What size of oil boiler do i need?

What Size Of Oil Boiler Do I Need?

When it comes to oil boilers, there are three main types - the combi, system and conventional. Within these types, you’d discover there happens to be a wide range of sizes to choose from. First and foremost, we must note that the size has to do with the amount of energy they offer to your heating and hot water system rather than the physical dimensions.

The rule of thumb is, the larger your house (which implies the more hot taps, radiators and showers), the more powerful (bigger) the oil boiler you’d require. For instance, a four-bedroom apartment with three showers occupied by a family of four will definitely need a more powerful boiler than a a bungalow featuring a single occupant.

It is, however, important to also note that it’s not all about going for the biggest oil boiler. If you decide to choose an oil boiler with a much bigger capacity that needed, not only will you be wasting money on the initial purchase as well as installation, but also lose money operating it. And in a converse scenario, if you go for the cheaper and lower-powered oil boiler in an attempt to save up some money, you’re most likely to end up with tepid radiators while also frequently running out of hot water. Hence, the importance of determining the appropriate size of boiler for your particular household before purchase.

To determine the appropriate size, determining the number of bathrooms, radiators as well as the total number of people living in the property would be a step in the right direction.

Numbers of Radiators Combi System Boiler Regular

Up to 10 24 to 27kW 9 to 18kW 9 to 18kW

10 to 15 28 to 34kW 18 to 26kW 18 to 26kW

15 to 20 35 to 42kW 27 to 40kW 27 to 40kW

What size boiler do I need?

The size of boiler you need will depend on the size of your commercial property, how many radiators and bathrooms you have and how appliances willl need hot water at the same time. 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.

can you replace storage heaters with electric radiators?

Can You Replace Storage Heaters With Electric Radiators?

The short answer to this question is yes. If your outdated storage heater is not heating your home the way it should, you’ll find a better replacement in electric radiators.

Being more modern and efficient, electric radiators offer a wide range of benefits which storage heaters can only dream of. Let’s have a look.

• Unlike storage heaters, electric radiators do not need to be charged up the night before which makes it totally controllable as you do not have to guess what your heating needs will turn out to be the next day.

• The above benefit leads to an even better one as the controllability quality of electric radiators makes them a lot more efficient than storage heaters. Electric radiators usually comes with programmable timers and thermostats which allows you to set various heating schedules for each of your rooms, meaning you’re only heating when and where its needed.

• Unlike some storage heaters, electric radiators do not cause wall blackening and also happen to more elegant and stylish.

• Electric radiators are not tough on allergies like storage heaters as they do not depend mainly on convection to heat

• Electric radiators also have an easy installation process with all you need to do to switch from storage heater to one being the removal of the former and inserting the radiators into the sockets.

However, if you want to make a switch to electric radiators, there’s the need to change to a standard electricity tariff from your economy tariff. And while the standard electricity tariff rates may be more expensive than the night time rate provided by Economy 7, the standard tariff rates are a bit cheaper than the daytime Economy rate. You’ll also get to use much less of electricity while also saving money on your heating bills and more.

how much is a new gas boiler?

If you’re thinking about getting a new gas boiler for your home or property, then you might also be wondering how much it’ll cost you so you can set a budget and start planning. As simple as this question sounds, it’s actually very tricky to provide a simple and short answer as the costs of installing a new gas boiler alone varies greatly based on the parts needed, the amount of work required, your location, their availability as well as the company you hire for the project.

When it comes to purchasing a new gas boiler the price you’re expected to pay also depends on multiple influencing factors such as the type, brand as well as your most preferred gas boiler model. However, one thing you should have in mind is the fact that your gas boiler is right at the heart of your home or property and can be a complicated piece of machinery. As a result, you wouldn’t expect gas boilers to come cheap. Generally, it’s going to cost within the range of £500 to about £2,500 to get a new gas boiler. Therefore, it’s always advisable to obtain all necessary details and facts before you decide to purchase a replacement gas boiler.

This price range may seem too high as it’s usually a turn off for most homeowners. However, it’s worth noting that gas boiler replacement costs and gas boiler installation costs are, more often than not, compensated by the saving you’ll make off your utility bills - all thanks to the new and more energy efficient boiler you just installed in your home. And even more importantly, when it has been estimated that roughly half of the amount spent on energy on an annual basis depends on your boiler.

How do I re-pressurise a boiler?

Re-pressurising your boiler means that you allow more water to enter system via the filling loop. It can be easy to re-pressurise your boiler yourself. Always check your manual, but there are some simple steps you can take to restore pressure to your boiler:

  1. Switch off your boiler and let it cool completely
  2. Make sure both ends of your filling loop are attached
  3. Open both valves to allow cold water into the system – you’ll hear it start to move
  4. Look out for your pressure gauge to show 1.5 bar
  5. Close both valves
  6. Switch your boiler back on
  7. Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!
How long does a boiler last?

If you get the right size boiler for your business and you get it serviced regularly, your boiler could last up to 15 years. It may even last longer than this, but you’ll find that your boiler begins to become less efficient as it gets older. Also, as technology improves, a boiler older than 15 years may not be the most efficient one on the market.

how to install nest thermostat?

Installing your Nest thermostat may not be as easy as screwing a light bulb, but we can also assure you that it isn’t very difficult either. However, if you lack the needed training or experience to pull it off, we’d recommend you hire the services of a professional in order to save yourself some time and money. This guide will give you some quick and easy steps to follow and ensure you make no errors during the installation process.

Once installed removing the Nest Thermostat can be done. To get started, you’ll need just a Philips head screwdriver which Nest has thoughtfully provided with the device.

• Turn off the Nest Thermostat by switching the circuit breaker to the off position.

• Label or mark your old thermostat’s wires. However, if you notice your thermostat is tagged 120v or 240v, or possesses thick wires, do not connect the wires to the Nest as you have a high voltage system.

• Uninstall the old thermostat by locating detaching the wires coming out from the wall into the thermostat. Once done, simply unscrew the device from the wall

• Mark the spot of your thermostat. Do this by threading wires through the Nest base plate’s centre incorporate the tiny bubble level. Once done, you can then use a pencil to mark te two screw holes.

• Attach the trim plate. If you wish to cover the screw holes, simply install the trim plate in the Nest box’s bottom to the base plate.

• Using the screws and screwdriver, attach the Nest base to the wall.

• Connect the wires to the Nest by putting the labelled wires in the Nest’s corresponding ports.

• Put the Nest display by lining up the connector on the display’s back.

• Turn on the power by switching the circuit breaker to the on position

• Connect your Nest thermostat to the WiFi network.

• Follow the on-screen guide and set the temperature.

• Use your smartphone or tablet to download the Nest thermostat’s mobile app to monitor and control your device remotely.

Can I repair my own boiler?

No. You must never repair your own boiler – only a Gas Safe-registered engineer can do any work on your boiler. You can do simple DIY tasks to repressurise your boiler or stop a leak, but if you have to remove the outer casing of the boiler or touch the flue then you must get a qualified boiler engineer to take a look at your central heating system.
