Property information for your heating design

The more accurate the plan you supply the easier the system will be to install.

Architect’s plans submitted in dwg or pdf format will most closely reflect the property layout.

Although we can work with plans which are not to scale (hand drawn, photographs, scans or estate agent plans) there could be a potential delay to your project. We ask that you annotate these with as many dimensions as possible to limit any delay.

Elevations show what the external walls of the property look like, to scale. As windows and doors lose heat at a higher rate than the walls we use these measurements to ensure the system is a correct fit for the space.

If no elevations are available, please let us know the dimensions of all the windows and external doors in each room.

Sections are a slice through the building. They can be useful to see ceiling heights or split level floors, and if any areas of the building are vaulted. Rooms with high ceilings will contain a larger volume of air to be heated, so we need to ensure this is taken into account at the desing stage.

If no sections are available, please let us know the ceiling heights in each room – paying particular attention to any vaulted areas. The standard ceiling height is 2.4m.

In order to accurately calculate the heat loss of each room we need to know how well insulated each element (walls, roof, ceilings, floor, windows) is.

New build properties will have to be insulated to a minimum standard in order to comply with Building Regulations. If your property is being built in excess of this, please let us know – this may be shown on drawings produced by your architect or on a SAP report.

For existing buildings, the more information you can give us the better. The age of the property can give us an idea of how it might have originally been built. You may even find that the building has evolved over the years, so any details on when different sections were built will assist the design.

A “u-value” is the measure of how well insulated an element is (the lower the value the better), so providing those would give us the most accurate information. If you don’t know an exact u-value, we can estimate this based on you describing the make up of each element – for example, “10 year old double glazing, or 300mm thick cavity walls retrospectively filled 20 years ago”.

For ease of installation we try to avoid going through walls and instead use doorways.

However, in certain situations this can result in very long pipe runs, from the manifold to the underfloor heating zone, compromising the system performance. If we can see a significant benefit from going through a wall we will do so, unless you specifically tell us not to.

A neoHub is an optional extra that allows you to control your neoStat or neoAir thermostats via smartphone or tablet over the internet.

Air source heat pumps (ASHPs) require a certain amount of free space around them in order to operate efficiently. As well as providing space for airflow, this space is also used as access for Commissioning/Servicing. You can find the make/model of ASHP on your quote.

Your ASHP will generally require a domestic hot water cylinder, and either a buffer tank or low loss header, as well as the controller and expansion vessels to all be installed internally. Often these are situated in a plant room, utility room or airing cupboard etc.

Please refer to your quote for the components specific to your system.

Guidance on required space for a plantroom.

A ground source heat pump (GSHP) system will generally consist of the heat pump, a domestic hot water cylinder, buffer tank and expansion vessels, which need to be installed internally.

Often these are situated in a plant room, utility room, store room etc. Please refer to your quotation for components specific to your system.

Air source heat pumps (ASHPs) can generally be installed under Permitted Development and do not require a full Planning Application. In order to qualify, the installation must comply with a certain set of criteria>

Please let us know what external space you have for ground collectors to be installed – the easiest way is to annotate a site plan. Your quotation will show our estimate for the size of area required.
