FAQ's

A whole house heat loss calculation is a design based on basic heat loss information. 

This takes into account the property volume, air changes per hour, insulation values for various aspects along with location and height above sea level to determine the design requirement. 

From the kWh design requirement we will be able to specify a suitable heat pump for your project. 

This will enable you to provide an estimate to your customer without having to undertake the full MCS design first. 

A fully compliant MCS design will encompass all aspects of the heat loss of a property, much like the whole house heat loss calculation. However, the full MCS design is undertaken on a room by room basis taking into account the specific insulation values of all elements internal and external including heat loss to neighboring rooms below, above or alongside.

SiZe Matters are proud to be fully MCS compliant for undertaking full heat loss designs, contact us to discuss your requirements. 

There are a number of ways for you to obtain a quote from Size Matters, firstly you can email directly to contact@sizematters-design.co.uk outlining your requirement or alternatively you can contact us by visiting our contact us page, here you will find a contact form and our phone number. 

We work with installers to ensure your heat pump is compliant with MCS and is suitable for your home. Unfortunately, there are many occasions where systems are not designed properly meaning that the heating is not running efficiently and therefore energy bills are incredibly high. Air Source Heat Pumps have received bad publicity as a result of this, however, they do work, and they work incredibly well when designed correctly.

You may already have an Energy Performance Certificate (EPC)  for your property which may show a heat loss calculation. Although this assessment will have been done to regulated standards it is not sufficiently detailed to be able to base a detailed system design on; it takes far less time to generate an EPC than it does to perform a complete MCS heat loss calculation, as such it is possible that the EPC will underestimate the actual heat requirements of your building. 

The MCS rules require that we follow the MCS standards for the heat loss calculation and system design for any system that will be MCS compliant. If your design is not MCS compliant then your system will not qualify for the Boiler Upgrade Scheme (BUS) payment. 

We must be involved from the very beginning as it is important that you provide your customers with a calculated heat pump size in order to quote as accurately as possible.

We offer a nationwide service, covering England, Scotland, Wales and the surrounding isles.

We survey every property unless there are drawings available (generally for New Build / Self Build properties) in which case we can work from those instead.

We are helping a number of people / companies who require assistance with an incorrectly designed or installed Air Source Heat Pump. We can provide you with an independent consultant report with our findings.

SiZe Matters has extensive experience in assisting developers in implementing renewable technology into their projects. SiZe Matters can undertake initial assessments to ascertain the requirement and find a cost effective solution to ensure your needs are met.   

SiZe Matters currently deals with a number of merchant chains throughout the UK.  We completely understand the installers needs and as such are ideally placed to work with our merchant partners.

We work alongside you to offer the level of support you require to enable you to retain and gain new customers.

One of the main benefits of the Microgeneration Certification Scheme (MCS) is ensuring that there is a very rigorous process in place for the system design and installation.  All MCS accredited companies are audited on an annual basis to ensure that these standards are being maintained.

There is no law to mandate MCS accreditation for a heat pump installation and before the Renewable Heat Incentive (RHI) and Boiler Upgrade scheme (BUS) where launched many heat pump systems were designed and installed where only crude heat loss calculations had been performed in order to save time and money.  However, many of these systems cost considerably more to run than the customer was initially led to believe, the short term savings from installing an underside system are massively outweighed by the increased running costs. 

We are proud to say that all of our heat pump designs have been in accordance with the MCS design criteria
