The website has been developed to make the specification of Vaillant products easier and simple for the Installer. It is necessary to confirm that you have read and agree with the following terms and conditions of use for this website each time you use it by clicking the check box on the log-in page.
The quick quote tool provides an estimate of heat pump requirements for budgetary purposes only. This initial budget is suitable for the installer to present a ‘ball park figure’ to the client before starting a more detailed site survey and calculations to produce a final quotation. When using the quick quote tool the installer should note that:
I. The heat loss calculation was calculated for the whole property using the following assumptions which therefore make the final result an estimation which is only suitable for budgetary purposes.
a. The property is assumed to be traditionally box shaped with an average ratio of internal wall, external wall, external doors, glazing, floor and roof area and ceiling heights for that particular property type.
b. The insulation U-values of the above fabric elements are given default values based upon the building regulations at the time of being built. A site survey is required to confirm these are accurate before producing a final quotation. The installer is able to make the necessary adjustments when using the website.
c. The room temperatures required are in line with those specified by CIBSE.
d. The ventilation figures used are in line with those recommended by CIBSE for the specific age of property.
II. In order to qualify for MCS certification the installation must comply with MIS3005 which stipulates an additional room by room detailed heat loss calculation is carried out in accordance with EN12831.
III. In order to comply with Vaillant’s installation standards an additional room by room detailed heat loss calculation is carried out in accordance with EN12831.
IV. The software is not able to take into account any site specific requirements. Therefore the installer should conduct a detailed site survey and consult the necessary planning manuals and installation instructions to ensure that all requirements are met.
To assist the Installer a number of parameters have been pre-populated with the likely input. It is the responsibility of the installer to verify that these are correct for the property in question.
V. To assist the Installer a number of parameters have been pre-populated with the likely input. It is the responsibility of the installer to verify that these are correct for the property in question.
VI. The outputs and recommendations produced by this design tool are based on the information provided by the user. It is the installers responsibility to ensure all data inputs are accurate.
VII. All product selections 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 Installer. Whilst Vaillant endeavour to ensure that our recommendations and designs accurately reflect our customer’s requirements, we are unable to accept responsibility for any loss incurred as a result of them failing to do so. It is the responsibility of the Installer to ensure the results are suitable for the property in question.
VIII. Domestic hot water storage requirements and the resulting predicted energy usage have been assumed based upon the number of occupants which is determined based upon the ‘number of bedrooms +1’. Running costs will vary if the actual occupancy level is different or if the user individual’s hot water consumption varies from the anticipated demand.
IX. Where solar thermal has been requested, recommendations are made on the assumption of sufficient roof area for installation of the required number of solar collectors. The draw off pattern is assumed to be optimal for the type of cylinder fitted . A more detailed calculation is required that takes into account the actual draw off patterns, orientation, solar volume, auxiliary volume and shading to accurately assess the running and energy cost savings.
X. Current fuel costs and boiler efficiencies in the existing property are based on information provided by MIS 3005 Reference material along with the Nottingham Energy Partnership. Heat pump electricity costs are based on the average available tariff. Heat pump efficiencies are based on efficiencies published in the Heat Emitter Guide for Domestic Heat Pumps. The space heating energy is calculated using the degree days for the nearest CIBSE location which assume that the temperatures are maintained at a constant level inside the property all year round.
XI. When a ground source heat pump is selected, an approximate land area or borehole requirement is provided for guidance only and assumes equal length pipe runs using MCS 002: Ground heat exchanger look up tables . In calculating the ground collector requirement, heat pump efficiency and run hours are based on building load data provided by the installer. Average ground temperatures are based on postcode from the average air temperature provided by for the nearest CIBSE city. Installers must check whether this configuration is appropriate for the specific site layout and carry out a detailed assessment and calculation of the actual requirement before committing on price and commencing installation. Installers must make the necessary adjustments to achievement the minimum Reynolds number in accordance with MIS3005 clause 4.2.15J and maximum pump energy power in accordance with MIS3005 clause 4.2.18.
XII. Vaillant does not sell directly to installers or end consumers. Installers should contact Vaillant for a list of stockists. Consumers should visit the  website for a list of installers.
XIII.Energy Cost assumptions
The Vaillant indicators and assumptions including energy cost assumptions will vary from time to time but with no prior notice to Vaillant calculator users. Potential cost-savings and any benefits are not warranted. Cost-saving computations are merely indicative: We apply your answers against estimated potential savings compared to other types of heating systems. The markets for gas, oil and electricity are subject to significant price fluctuations and pricing variations between energy suppliers. We cannot compute any actual cost saving or cost increase applicable to your property based on your data entry. We cannot compute any actual cost saving relative to any commercial user discounts or group user discounts which you may negotiate with energy suppliers or which you may be eligible to claim.
For comparative energy costs, we use data published by Nottingham Energy Partnership. This comparative cost data is historic and is liable to be updated. We shall endeavour to publish a link to the then current Nottingham Energy Partnership data on our website for the Tool. We will update the Vaillant calculator to take account of any updating by Nottingham Energy Partnership of its comparative cost data as soon as practicable. We are not responsible for any aging, errors or omission in Nottingham Energy Partnership’s data.
Energy cost data shown is based upon the indicative costs per kWh of energy, Vaillant energy cost data being based upon the indicative cost of electricity. Actual energy costs are a market variable. Any RHI benefits are indicative and estimates only.
XIV. The quotation states which products are available from Vaillant, the installer should take into account that addition materials purchased from others will be required to complete the installation. Quotations contain list prices, the installer should contact their stockist to get the actual price for the equipment. Quotations are valid for 1 month from the date the report is emailed or printed to PDF. Installers should check stock availability as from time to time Vaillant will discontinue specific ranges to best meet the needs of the market.
