Central Heating Tools


Solving Problems With Blocked Central Heating Systems


Using a power flusher pump

Over time both commercial and domestic central heating systems will require some maintenance and repair work undertaking to key components including the heating boiler, water pump, valves, radiators, pipework, and thermostat.

One of the most common problems experienced by homeowners and business users is the build up of harmful deposits of oxide and sludge that prevent the components working efficiently.

When things reach a certain level the only option to resolve this problem is by either replacing the heating system components on a one by one basis (every affected pipe, pump, valve etc) or by way of power flushing.

What is a Power Flush?

A power flush is the task of cleaning out the central heating system by circulating high volumes of (forced) water and cleaning agents (detergents) around a heating system to remove debris, rust, oxide deposits, sludge etc.

You may need to have a power flush done if you have cold spots in your radiators, or your radiators are cold at the bottom and warm at the top. Occasionally one radiator in your system may not be working at all and this is a sign that a power flush may help.

If there is a build up of sludge in the systems feed and expansion tank or the heating system is very slow to build up to temperature these are both indicators that a system flush clean is required. Another indicator of the need for a power flush is if your thermostatic radiator valves are stuck in the off position.

Central Heating Power Flushers come in various sizes which range from models with a small tank which is enough for a standard domestic heating system to industrial sized units which will flush out a system in the largest of commercial properties.

Power flushing pumps can be hired from your local tool hire shop. 

If you are a professional plumber this piece of plumbing equipment can also be purchased from outlets specialising in this type of equipment.

To begin a flush on a central heating system you will need to isolate your electric power supply to the system. Do not remove your earth continuity bond. Close both isolating valves that should be on either side of your central heating pump. You are then in a position to be able to disconnect the water pump from your system. You can now connect your central heating power flush system to your central heating system if your power flusher comes with a connecting manifold.

Alternative type of connection:

With other types you can connect the power flusher to your central heating system via your radiator valve connectors.

To use this type of power flusher turn off your radiator valves, disconnect one, allow the air bleed valve (the one used to bleed radiators) to be open so air can come into your radiator and water out from the disconnected valve. When all the water has drained from the radiator you can now connect your power flush to the return valves on the connections of your central heating system.

Electric Powered Chainsaws

An electric powered chainsaw is the ideal piece of powered garden machinery for general logging, prunning, and cutting back work in the garden or workplace.

Although the use of this type of saw is restricted somewhat by the need for the tool to have a trailing electric power cable it more than makes up for it by having far reduced maintenance needs than its equivalent petrol powered models.

After fitting a chain bar and loop chain an electric chainsaw only needs filling with chain saw oil and its power supply connecting to be ready for use. No engine warming up is needed, no fuelling or mixing petrol with oil, no choke setting adjustment before use, you can virtually instantly get to work sawing, chopping, logging, and pruning.

A wide choice of electric chainsaws are now available to buy including budget priced models for occasional use, branded home user ones aimed at the home gardener, and also top end price models such as those manufactured by Makita and Stihl as examples.

The majority of electric chainsaw are powered by a 240v electric power supply. There are a few machines however that are available in 110v variations for use on site when it is neccessary to run off off a standard power tool transformer.

Most chain saws of this type are fitted with a chain bar and cutting blade of the size range of 12" to 16" in length. This is the ideal ratio of cutting capacity matched to an electric driven saw of this type.

A large advantage for the home gardener that only needs to use this type of powered garden machinery occasionally (perhaps once or twice per year) is the lighter weight of an electric chainsaw when compared to an equivalent petrol fuelled model. The weight saving is a real advantage especially when the saw is used for repeated periods of pruning and trimming back work in the garden.

When you are looking to purchase a chainsaw perhaps the best question to ask yourself is how often you will use it? For the home user that is undertaking cutting work close to the family home or other property the best consideration has to be a straight forward electric chainsaw.
