Going Beyond Heat Loss

Bivalent Design

Select the ideal set point for your bivalent system.

After completing a heat loss for the property, you will be able to pick the optimum external design temperature for the fossil fuel boiler to operate, therefore providing a solution for a heat pump bivalent system. A great steppingstone for some properties wanting to transition to reducing carbon emissions and fuel waste.

Pipe and Pump Sizing

Quickly size your primary pipes or heating distribution.

Without drawing a plan, you type in the lengths of pipes the system informs you what dimeters are suitable based from the heat loss, velocity and pressure loss. Use the Grundfos pump sizing tool in collaboration with the results obtained.

Emitter and radiator sizing

Automatically determine the correct size for your system.

Our radiator and emitter step will guide you through what type and size should be used based on flow and return temperatures. Indicating to you in green which rooms have acceptable emitters either current or proposed.

CAD Design

Measure Rooms using CAD tools.

You don't need other CAD packages and can stop printing out your PDF drawings. The moment you start to measure with the quick select tool all dimensions will quickly apply to your room by room heat loss survey.

MCS Heat Pump System Performance

Helping to provide certification for your installations.

Within your dashboard there is an MCS Assist. Providing you with the compliance certificate and performance estimate for all your heat pump projects. Use the autofill feature; information from a heat loss report automatically populates this information so you don't have to.

Quick Property Estimator

Domestic or commercial heat loss.

Enter details for a property such as total area, number of floors and pick building material for the software to provide a whole house heat loss. Great to support your quotations before you complete a room-by-room heat loss. Feedback from our customers is that the results are 5% accurate from the final room by room heat loss.

Our Digital Supply Chain

With our digital supply chain, you can directly link your heat loss and design reports to your favourite manufacturers and merchants. Asking them for assistance and increase you confidence in the correct design and aid your purchase orders.

Don't Just Take Our Word For It

"We have been using Heat Engineer software for just over a year now & it's transformed the way we conduct our heat loss surveys! Its simple to use and understand, providing accurate and professional reports first time every time. Heat Engineer are continually improving and evolving the software for a better experience adding many great new features to make our jobs even easier. Well Done Team Heat Engineer."

Ross Mckenzie Ltd

"Because of your product: I have reassessed what I install how I install it and what the outcomes of my install will be on the environment. I now preach this to my client base and look to influence all builders and developers that I deal with daily. I get told: As long as it works do what you need to…. the will is there but sadly people like me were devoid of the resource and support to bring this forward. A pathway to a more sustainable future is what you should call your product. Again it is bigger than the sum of its parts…a doorway to environmental awareness and heating system design. I have since: retrained on ASHP and am completing the Daikin academy course."

Walsh & Son Ltd

"Heat engineer is an essential part of my tool kit. Ease of use and the time it saves on heat loss calculations is essential to me. It enables me to spend more time talking with my customers answering their questions and building a rapport with them. Results software produce are brilliant, along with looking extremely professional with my businesses personal touch. Fantastic software that all serious engineers need in their toolkit."
