Rerouting new pipework can add considerable expense as well. Beware of companies taking shortcuts, or indeed, charging more for lifting carpets and floorboards. Also note, there are strict rules regarding how pipework is laid in joists and how far you can cut into them. There is a maximum size the ‘notch’ can be cut in a joist and care should be taken. All pipework should be laid or clipped properly and to current standards, not left hanging loose. Resiting a boiler Introducing the PlumbShark: A Premium, Patent-Pending 10-in-1 Plumbing Multi-tool Keyring, Expertly Designed for UK Plumbers, Heating Engineers & DIY Enthusiasts. It's unique shark-shaped design is not only eye-catching but also a testament to the exceptional quality of this tool. 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.
Isolation valve/pump head tool: Bleed pumps or turn off slot heat valves with ease using this tool, saving time and hassle. Therefore, if your current gas-fired combi boiler was installed after Apri 2005 you will already have upgraded 22mm gas pipework running from the gas meter to the boiler and you won’t have to worry about any pipework modifications if you are after a simple combi boiler to combi boiler replacement. This, of course, assumes your current boiler was installed correctly. Some exceptions Powerflushing – probably the biggest and most expensive con going and a subject that really bugs me. I’ve never come across a system that ever needed a power flush and I have never power flushed a system and I doubt I ever will. What is power flushing?

Apart from being a legal requirement under Building Regulations, a system cleanse is important to ensure the manufacturer’s guarantee remains valid. If you think of it in terms of buying a new car, it’s unlikely you would use the oil from your old car to run your new engine. Debris, rust, and other contaminants can damage your new boiler and reduce its efficiency.

Adding thermostatic radiator valvesIdeally, 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 home > manufactures list > Heating Domestic & Commercial > Industrial Sundries > Gas Meter Accessories There’s something called the Energy Companies Obligation (ECO) scheme which is run by the government. Under this scheme, some homeowners and private tenants are eligible to have their inefficient boilers replaced either completely free or have the cost heavily subsidised.
If your boiler breaks down and you need to fork out for a replacement, you might be able to save money by claiming some sort of grant, or even getting it free – if you’re eligible that is.The layout of your current system and whether you want to keep it the same or upgrade to a different system will have a huge effect on the final cost of the work. Upgrading your system Now in this example we are using a household cooker to demonstrate this topic. On a cooker you should be testing the three biggest rings, so the next step is to light those up on the cooker itself. All other appliances will have their maximum rate determined by the manufacturer.

If you’re turning the wrong valve then you’re probably causing problems with how the system is ‘balanced’ and might have some radiators not hot enough and others too hot. An installers job, having fitted new central heating, is to balance the system. If the wrong valves are turned this can sometimes cause problems. 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. An experienced engineer will be able to offer you the best solution, the most efficient boiler for your needs and be able to save you money not only in the short term but also in the long run.
