Is it time to go Low?

Low Carbon is very much on the agenda in particular with with the imminent introduction of the BUS (Boiler Upgrade Scheme) in less than 24 hours.

We felt as Grant G1 Installers, it was timely to pop out a brief post in relation to some very simple points that sometimes still get overlooked.

Working with Grant UK recently, on some harder to treat properties, as well as some of the basic

information required to help make the best choices, helps remind all of the need to start simple and work through the correct process.

In short is a heat pump suitable for a hard to treat property? The answer simply sits in the design.

We ensure that every single system we install is designed to MIS3005 standards as a minimum, this helps ensure that the technology application will meet the current building regulations, as well as the standard, and that the required comfort levels and energy savings should be achieved, this is why it's always best to design before you decide. Don't always rule out hard to treat properties based on rumours and non-factually based comments.

Is the property suitable for a heat pump?

When considering a heat pump, it is important that any heat loss from the property is minimised. For many homes built in more recent years, their levels of insulation should be sufficient, but with older properties, it may be necessary to improve the insulation so that any heat currently being lost through the walls, roof and floor can be reduced.

Improving the insulation of the property will not only make it better suited to a low-temperature system, such as a heat pump, but it will make the property more energy efficient. There are lots of ways you can improve the heat loss of the property and one of the easiest ways is loft insulation. By laying 270mm of insulation in the loft, one can then hopefully achieve the required u-value of 0.16W/m2k which is needed.

Loft insulation is cost effective, and simple to increase to the 270mm required level for maximum efficiency gains.

Insulating a property’s walls is another way to reduce the amount of heat that escapes a home. Cavity walls are relatively simple to insulate because they can be drilled into and the insulation injected within. Solid walls are trickier to insulate but they can either be clad with insulation on the outside or have insulation attached inside instead.

Another step that building owners can take to improve the insulation of their properties is by installing double glazed windows. Heat can easily escape a home via the windows so by improving their glazing, to either double or even triple glazing standards, the property will not only be warmer but you will probably find your energy bills will reduce too because less heat energy is being lost.

How to maximise the efficiency of your heating system

Every building is different and a solution for one type of property may not suit another but there are plenty of products available that building owners can install in their properties to not only deliver their heating requirements sustainably but also with greater efficiency.

An air source heat pump is a renewable heating system, and they are also incredibly efficient.

Provided the unit is installed and set up correctly and the system has been designed with suitably sized heat emitters and heat loss from the property is minimised, an air source heat pump can perform at incredibly efficient levels. For example, the Grant Aerona³ 6kW model gives over 4kW of energy into the heating system for every kilowatt of energy it uses to operate and they are incredibly quiet too!

Just see our website for examples of this in action.

A heat pump’s efficiency can be further improved when it is combined with suitable complementary technologies. A high efficiency heat pump cylinder which features a larger internal coil will help transfer the heat from the system to the domestic hot water as efficiently as possible. By installing a suitable heat pump cylinder, such as a Grant QR cylinder, this can help the heat pump to operate at its best.

Finally, the addition of a Solar Photovoltaics with or without Battery Storage, or Solar Thermal systems alongside a Heat Pump, can further improve the overall efficiency of the whole heating system.

Even on cloudy days, Solar PV and Thermal can fulfil a significant proportion of the hot water demand which in turn reduces the demand on the heat pump when connected to the appropriate third party technology.
