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

If you choose to install an LPG boiler, you’ll need to find an LPG supplier. They’ll deliver fuel to you every time your storage tank runs low. You can even rent a storage tank from them if you don’t want to buy one. Make sure you know who your local suppliers are and where they are based.

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:

• Switch off your boiler and let it cool completely

• Make sure both ends of your filling loop are attached

• Open both valves to allow cold water into the system – you’ll hear it start to move

• Look out for your pressure gauge to show 1.5 bar

• Close both valves

• Switch your boiler back on

• Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!

Are Electric Radiators Expensive To Run?

Just like many home additions, the running costs of electric radiators varies largely on a number of factors. Great number of electric radiators typically comes with an in built thermostat which is designed to turn itself off automatically when not in use in order to save energy.

However the energy provider’s set electricity charge tariff will also have a great influence on an electric radiator’s running cost. Let’s take a look at the running costs of an electric radiator!

A 600 Watt electric radiator ( on a standard electricity tariff) will usually have a running cost ranging between 4 to 6 pence each hour. However you should also take note that this scenario might change in situations whereby the electric radiator is not calling for heat the full 60 minutes of each hour. And this is more likely to be the situation as the thermostat is programmed in such a way that enables it to turn itself off immediately there’s an achievement of your required room temperature level - usually within 10 minutes from the time it was switched on. As a result of this, the running cost per hour of electric radiators will be greatly reduced to just about 1 to 2 pence.

It’s also important to note that enhancing the insulation of your home can go a long way to add to the heat retention value of each room. Consequently, the duration at which the electric radiator calls more heating will be significantly reduced, which in turn, implies a lower electricity bill.

Another key factor that can play a huge role in saving on your heating bills is the programming as well as usage of your electric radiators. Every radiator comes with an independent digital thermostat with a number of 24/7 programming options to help achieve maximum efficiency. When the radiator is properly set according to your lifestyle, you can save as much as 50 percent on your heating bills.

How Do You Bleed An Oil Boiler?

Bleeding air between the oil supply and an oil fired boiler’s burner is a process that’s often required when the system has run out of oil and the burner has stopped working. Upon refilling the oil tank, the air that has been trapped within the oil pipe when empty has to be freed to ensure that the oil reaches the burner and allows it to start again. So how do you go about the process?

First and foremost, it must be noted that it’s always better to be on the look out for the amount of oil in your fuel tank and get it refilled before it runs out. However, if it does run out, you can take the following steps:

• Identify the burner

The burner is a red plastic cover and it’s usually positioned on the bottom part of the boiler (mostly inside the boiler casing). Once identified, inspect it to see if the lockout button is lit red. If yes, simply unscrew and detach the burner’s red case using a flat head screwdriver.

• Identify the oil pump

You’ll find the oil pump on the burner’s left side which is connected to the flexible oil line. Once done, simply locate the 3 inches long hexagonal stem protruding from the pump and with a small threaded plug screwed into the end. Unscrew the plug in just half a turn ( 180 degrees) with a 4mm Allen Key. At this stage oil will be released, do ensure there’s a cloth or rag underneath the plug to grab the oil freed.

• Press the lockout button

This is the next and final step. However it’s also crucial to note that the burner fan will run for about 12 seconds and discharge some oil from the loosened plug which you can grab with a cloth or rag. Immediately you hear a buzzing sound, use the Allen key to tighten the plug. If enough air has been bled, the system will fire. But if not, then you’ll have to repeat the process again.

To ensure your boiler is functioning efficiently and to keep your home warm, it’s important to see that your boiler is serviced on a regular basis by a licensed boiler engineer. Failure to do this can result in sudden boiler breakdown which can be a hard hitting blow to one’s financial power especially when there’s no boiler cover to cushion the blow or totally avoid it all together.

When your boiler is covered, it implies that you’re protected in the event whereby your boiler or it’s controls malfunctions or break. Several boiler cover will include the servicing cost, while some may not so it’s advisable to always go through the details, no matter how small, before entering into a boiler cover agreement. Typically, a boiler cover will cost between £60 to £100 per year and the payment is made on a monthly basis. Various boiler insurance companies have varying cover cost, however, here are the common boiler cover policies:

• Homeserve charges from £13 per month

• EDF Energy costs from £13.29 per month

• British Gas from £12 per month

• Scottish Power from £13.13 every month

• CETRI UK charges from £13.50 every month

• 24/7 home rescue costs from £9.60 every month

• Gorgi Home Plan costs from £6 per month plus 3 months free

• Your repair charges from £9.60 per month

• NPower Boiler Cover costs from £10.92 every month

• SSE Boiler Breakdown Cover charges from £4.95 every month

It’s important to note that sometimes you have the option of adding your boiler cover to your existing home insurance, if you do not want a standalone policy for your boiler cover. In many scenarios, this is referred to as an extra or add on service referred to as “Home Emergency Cover. When compared to the standalone boiler policies, this is usually a lot cheaper as it comes in around £5 per month.

In recent times, home and property owners are constantly looking for ways in which to enhance both energy efficiency and sustainability especially as the world draws closer and closer to energy-efficient technology. The Nest thermostat is a great example of this fact as its designed in such a way to save energy while also cutting heating and cooling costs. And an interesting fact is, you’re not limited to using just a single Nest thermostat in your home as multiple of the device can successfully run together to maintain a consistent level of temperature monitoring as well as energy efficiency. What’s more? You can add up to 20 Nest thermostat and 18 temperature sensors in a home.

It’s very unlikely that you’re going to need this many thermostats in your home, but if you’d like to add a second the process is quite straightforward. However, we’d recommend you employ the services of a seasoned professional especially if you lack the required training or experience to pull this off to save yourself some time and money.

To get started, simply download the associated Nest app to add Nest devices. Now let’s have a look at the processes involved in adding a second Nest thermostat to your home.

• Go to the top right corner and select the “settings.

• Once done, then click on the Add Product “Plus button.

Upon a successful addition of the second thermostat, the app will guide you through the initial set up steps. Google also offers a very helpful guide if you’re unfamiliar with the initial configuration.

When your boiler is being replaced you won’t have hot water or central heating. If you don’t mind this you can stay in your home, and use portable electric heaters if needed. Most installers undertake a power flush before installing a new boiler now and this can cause muck and debris from the pipework, so you may wish to get out of the way while this is happening!
