Precision Engineering | MCS-Compliant | Independent System Specification
Air Source Heat Pump (ASHP) Design
A heat pump is only as efficient as the design behind it. We provide full, room-by-room heat loss calculations to ensure your new system is perfectly sized for your home’s unique thermal footprint.
MCS-Compliant Calculations: Our designs follow the strict MIS 3005 standards. This is essential for ensuring your system is eligible for the £7,500 Boiler Upgrade Scheme (BUS) grant.
Performance Estimations: We provide clear data on expected running costs and seasonal efficiency (SCOP), so there are no surprises when the winter bills arrive.
Radiator & Pipework Analysis: We check your existing emitters to see if they are "heat pump ready," recommending upgrades only where the data shows they are truly necessary.
Solar PV & Battery Storage Design
Maximise your energy independence with a bespoke solar layout. We don’t just look at your roof; we look at your consumption patterns.
Shading & Orientation Analysis: Using local East Anglian weather data and site-specific shading analysis, we predict exactly how much energy your panels will produce.
Battery Sizing: We help you decide if battery storage is a viable investment for your lifestyle, ensuring you store power when it's cheap and use it when you need it.
Inverter Specification: Technical advice on the best hardware to bridge the gap between your panels and your home’s electrical grid.
Why "Design-First" Matters
By investing in an independent design from Tawai Consulting before you buy hardware, you gain:
Lower Running Costs: A correctly sized heat pump uses significantly less electricity.
Installation Confidence: You can give our design to any installer to get an accurate, fixed-price quote.
Longevity: Systems that aren't "short-cycling" (turning on and off too often) last years longer.
