If your installer is pushing you towards getting a power flush I would be very wary of using them. What is a system cleanse Measuring mains water pressure alone will not provide a complete picture of whether a combi boiler will work well or not, the flow rate is very important as well. NatWest, Royal Bank of Scotland (RBS) and Ulster Bank, which are all part of the NatWest Group, will now shut at least 172 of their bank branches in 2023 and 2024.

1. Your budget – grants, loans, and other schemes

Ideally, you should clear all space around the areas where you anticipate access will be required to make life easier for the installer. 5. Your hot water demand – bathrooms, ensuites etc

The test is now complete! The only part of the installation not tested for Gas tightness is the test nipple itself. To do this have some leak detection fluid/spray handy and apply it to the nipple and open the gas supply once more. If there are any leaks the spray would bubble up. Turn the gas supply off for a final time and wipe of any excess leak detection fluid. Does it work? Yes, pretty well. Sludge is ferrous in nature (meaning it contains iron) and so it can be trapped by a powerful magnet. However, sludge can also occur from non-ferrous metals such as copper, zinc or aluminium components, and because this is non-ferrous, the magnet will not catch these particles. Asking a lot of questions can inspire confidence in the engineer depending on their actions and answers and it’s a good way to gauge competence. If you’re unsure which way new pipework will be routed then ask! Analysing your quotes YouTube sets this cookie to measure bandwidth, determining whether the user gets the new or old player interface. An important part of the commissioning of a boiler is explaining to a customer how the boiler and associated controls work. A new boiler and controls could consist of the following:

7. Upgrading your pipework – gas and water pipework

You can either go with our advice and research from the 3,100 respondents or go with your installers choice of boiler. Every installer will have their own preferred boiler, one that they’ve installed the most, repaired the most and consider best overall. Cheaper boiler or better guarantee? If your flow rate is less than 10 litres per minute then you have a low flow rate. If your flow rate is 10-15 litres per minute then you have an acceptable flow rate. If your flow rate is above 15 litres per minute then you have a good flow rate. if you’re having a new gas-fired combi boiler installed then there is also an additional legal requirement to install (at least) one of the following: There have been lots of articles on the dubious subject of power flushing, here’s a link to a few of them: Contract pricing and quantity discounts available on gas meter accessories, our contracts department

If you’re considering going up into the loft and adding an ensuite bedroom or extending to the side of the house in the near future, then you should consider a bigger boiler than your current demands dictate.If you have an ensuite bathroom as well as a main bathroom you’ll sometimes be using the two showers at the same time. A few combi boilers can just about handle the hot water demand but only just about. It’s likely you’ll have a system or regular boiler in your property.

One thing to stress is you mustn’t be afraid to ask questions if you don’t understand anything or if you disagree with anything. It’s your home and you’re the one spending the money – so don’t be afraid to ask what the process is and why the engineer is recommending something. NatWest, RBS and Ulster Bank to close at least 172 branches in 2023/24 – here's the full list, plus alternatives If you have a regular or system boiler (i.e. a boiler that also uses a cylinder, hot water tank, expansion tank in the loft) and want to convert to a new condensing and efficient combi boiler then additional pipework modifications will need to be made. Often the hot water tank is in the landing cupboard or bathroom or other inconvenient place and you might want it out of the way.Older gas-fired combi boilers (those installed pre-April 2005) were non-condensing and required only a 15mm copper gas supply pipe to make it run efficiently and safely. Newer, condensing boilers (installed after April 2005) usually require a 22mm copper gas supply pipe to make them run efficiently and safely – this is because they require gas at a higher pressure to be able to run at their most efficient. You may have heard about the Warm Front scheme but this was replaced by the Affordable Warmth Obligation. It’s part of the ECO scheme and provides help with the cost of replacing or repairing your boiler, as well as help with other energy-saving measures. They also offer advice and tips on other upgrades to your heating. Now, that’s not bad at all considering the average UK household uses an average of 3,000kWh. However, because the boiler cannot store the electricity it is producing, it needs to be used at the same time it is being produced. That means you might not be receiving the full benefits of the saving if you have a smaller property, with fewer people living in it, using more electricity than the average household.
