Room Design Temperatures

All Heat Pump (Air, Ground or Water Source) installations are required to be designed in compliance with MCS to be eligible for any government funding and/or incentives. The designing process entails Heat Loss Calculations to be carried out to ensure the equipment being installed is sufficient to meet the properties space heating and hot water demand.

Room Design Temperatures

Below are the internal design temperatures for relevant spaces which are used to maintain compliance with MCS. These temperatures are also in line with the UK national annex to BS EN 12831. All rooms will be designed with a flow temperature of between 35-55c depending on the heat emitter servicing the rooms heat demand.

Please select yes to all the room temperatures below that you are happy with.

Please note, these temperatures are minimum design temperatures that must be used to ensure compliance. However, they can be increased above those stated below where required. Please advise the surveyor which rooms you desire to be warmer and to what temperatures so that the design can be completed accordingly.

Planning Permission

The Planning Portal states the following information relating to the installation of Air Source Heat Pumps:

"From 1 December 2011 the installation of an air source heat pump on domestic premises is considered to be permitted development, not needing an application for planning permission, provided ALL the limits and conditions listed below are met.

These permitted development rights apply to the installation, alteration or replacement of an air source heat pump on a house or block of flats, or within the curtilage (garden or grounds) of a house or block of flats, including on a building within that curtilage. A block of flats must consist wholly of flats (e.g. should not also contain commercial premises).

Limits to be met:

-Development is permitted only if the air source heat pump installation complies with the Microgeneration Certification Scheme Planning Standards (MCS 020) or equivalent standards. Read more about the scheme

-The volume of the air source heat pump’s outdoor compressor unit (including housing) must not exceed 0.6 cubic metres

-Only the first installation of an air source heat pump would be permitted development, and only if there is no existing wind turbine on a building or within the curtilage of that property.

-Additional wind turbines or air source heat pumps at the same property requires an application for planning permission

-All parts of the air source heat pump must be at least one metre from the property boundary

-Installations on pitched roofs are not permitted development. If installed on a flat roof all parts of the air source heat pump must be at least one metre from the external edge of that roof

-Permitted development rights do not apply for installations within the curtilage of a Listed Building or within a site designated as a Scheduled Monument

-On land within a Conservation Area or World Heritage Site the air source heat pump must not be installed on a wall or roof which fronts a highway or be nearer to any highway which bounds the property than any part of the building

-On land that is not within a Conservation Area or World Heritage Site, the air source heat pump must not be installed on a wall if that wall fronts a highway and any part of that wall is above the level of the ground storey.

In addition, the following conditions must also be met. The air source heat pump must be:

-Used solely for heating purposes

Removed as soon as reasonably practicable when it is no longer needed for microgeneration

-Sited, so far as is practicable, to minimise its effect on the external appearance of the building and its effect on the amenity of the area.

You may wish to discuss with the Local Planning Authority for your area whether all of these limits and conditions will be met."

Heat Loss Property Information Form

Boiler Upgrade Scheme For the property to be eligible for the Boiler Upgrade Scheme (BUS) the property must satisfy the following:

-Have cavity wall insulation (if the property has cavity walls).

Loft insulation meets one of the following:

The National Insulation Association recommended depth for loft insulation is:

-270 millimetres for glass wool, -250 millimetres for rock wool -220 millimetres for cellulose.

You must install loft and/or cavity wall insulation if it is recommended in your EPC.

All EPC’s have a section which outline recommendations of methods to improve the efficiency of the building. If there is a recommendation to install loft insulation or cavity wall insulation this must be done prior too the application of the BUS voucher and a new EPC completed to reflect the change. All other recommendations present on the EPC such as upgrading glazing, floor insulation or external/internal wall insulation etc. are not a requirement of the BUS scheme and are optional.

On occasion, there may be instances where it is not possible to install either loft or cavity wall insulation (or both). When this is the case, exemptions can be provided to enable eligibility for the BUS. Further information on how to obtain an exemption can be found within the Essential Guide for Applicants link below.

Project Address:

Project Reference: RC1827

This property is a 4-bedroom end-terrace house built originally in 1998. The property has undergone a side single-storey extension in 2014. The property is located within a conservation area. The external walls are filled cavity (as built). The ground floor is solid, assumed uninsulated except with an extension is assumed insulated. The property has got UPVC double glazing throughout, the rear ground floor windows replaced in 2023. The intermediate floors are assumed uninsulated concrete except the living room above the garage is assumed insulated. The loft space has got 250mm of insulation present within the joists.

The current heat source is mains gas delivered through a standard boiler located wall-mounted within a kitchen cupboard. The current hot water cylinder is located within a cupboard of bedroom 3 on the second floor. The incoming mains and consumer units are located within the garage. The property is heated by predominantly radiators, all of which appear to be on standard 15mm pipework. The kitchen has recently had wet underfloor heating installed at assumed 150mm centres. The underfloor heating manifold is located within the hall cupboard. The property benefits from 22no Solar PV panels (6kWp) as well as 2no Solar Batteries. There is an Eddi hot water power diverter present on the system currently.

The location for the ASHP outdoor unit is currently undecided, but two locations were discussed as follows:

Option 1 – to be wall-mounted along the side external wall of the living room above the flat roof of the extension at first floor level. This is ’s preferred location as the ASHP will be out of the way. Clarification on whether planning permission would be required will be needed as the property is within a conservation area and the ASHP may be visible from the roadside.

Option 2 – to be ground mounted at the rear of the kitchen/sitting room. does not prefer this location due to it being within the garden area.

The new hot water cylinder is to replace the current cylinder within the cupboard of bedroom 3 on the second floor. It is worth noting, there is restricted floor to ceiling height in this cupboard due to the sloping ceiling. The access door into this cupboard is also only 500mm wide so alterations may be required to accommodate the new cylinder installation.

is aware that the radiators may require replacing in order for the ASHP to work efficiently and provide the necessary room temperatures. Mr Gee is open to discussion regarding this once the requirements are known.

The heat demand of the property based on the above information is 8.150kW. So, the 12kW Midea Monobloc R32 ASHP would be required alongside a 225L cylinder (based on being 4-bedrooms). The emitter/radiator schedule has been completed based on a 50°c flow temperature.

A new radiator has been sized for the second floor landing as this space is currently unheated. A type 33 radiator has been suggested for the second floor bathroom due to the restricted space and high demand.

General and delivery access to the property is good. There is parking on a private driveway for 3+ vehicles.
