Fuel costs and boiler efficiencies are based on information provided by Sutherland Tables. Heat pump efficiencies based on detail efficiencies published in the Heat Emitter Guide for Domestic Heat Pumps.
GROUND COLLECTOR DETAILS Ground collector requirements Estimated ground collector land area requirements and assumptions made in our calculation are as follows: Ground collector type: Land area required: Ground conductivity: Thermal conductivity: Pipe specification: Pipe spacing: Pipe depth Heat transfer fluid: Horizontal 514.73 m² Average 1.40 W/mK 25mm OD SDR11 0.75mm 0.8-1.2m 25% mono-ethylene glycol The land area quoted is provided for guidance only and assumes equal length pipe runs. Installers must check whether this configuration is appropriate for the specific site layout and make adjustments accordingly in relation to achievement of the minimum required Reynolds number in accordance with MIS3005 clause 4.2.15J and maximum pump energy power in accordance with MIS3005 clause 4.2.18. In calculating the ground collector requirement, heat pump efficiency and run hours are based on building load data provided by the user. Average ground temperatures are based on postcode. To comply with the requirements of MIS3005 a detailed ground collector requirement assessment must be made using appropriate look up tables or approved software.

ASSUMPTIONS SUMMARY Assumptions made in our calculations Heat losses have been estimated using pre-set u-values specific to the building age selected and any adjustments made by the user during the data entry section of the heat pump selection tool. Domestic hot water requirements have been determined by the number of occupants (number of bedrooms +1). Where solar thermal has been requested, recommendations are made on the assumption of a south facing roof and sufficient roof area for installation of the required number of solar collectors. Smartrad selections are based on assumed typical room types/sizes for the property type selected and may not accurately represent the specific property. Fuel costs and boiler efficiencies are based on information provided by Sutherland Tables. Heat pump efficiencies based on detail efficiencies published in the Heat Emitter Guide for Domestic Heat Pumps. Product selections from the Quick Quote tool are intended to provide an estimation of the likely heat pump and other system components needed to meet the specific project requirement in line with the information provided by the user. It should be noted that in accordance with MIS3005, an additional room by room detailed heat loss calculation in accordance with EN12831 must be carried out and the recommendations herein should be used for budgetary purposes only.
