How Does This Impact Sizing?
• Typical house
– 50,000 BTU Heat Loss
– 30,000 BTU Heat Gain
– Sizing of T THERM GEO
– Select 4 Ton two stage
– Heating capacity is 44,420 BTU so we are sized for 89% in
heating
– The homeowner will need to use resistance heat at -10 F
– Cooling capacity is 46,100 BTU (1st stage) so we are oversized
by 65% which is fine due to our deep coil, cooling
dehumidification will not suffer
10. When COMFORTmatters
How Does The
Competition Size?
• Same house
– Sizing of other manufacturer
– Select 4 Ton
– Heating capacity is 36,500 BTU so we are sized for 73% in
heating
– The homeowner will need to use resistance heat at 4 F
– Cooling capacity is 38,500 BTU (1st stage) so we are
oversized by 28% which beyond the recommended max
oversize of 25%.
11. When COMFORTmatters
If We Follow
Recommended Sizing
• Same house
– 25% Maximum cooling over sizing
– Select 3 Ton
– Heating capacity is 26,500 BTU so we are sized for 53% in
heating
– The homeowner will need to use resistance heat at 22 F
– Cooling capacity is 27,500 BTU (1st stage) so we are
undersized by 8% which is within the recommended max
oversize of 25%.

– Smart - Incorporate 30 years of geo knowledge
Building a better Heat Pump
Our job is to find the best products for you – our dealers so you can focus on your customers
Quality is an absolute must have but we couldn’t just assume it was present
Dependable – again an absolute must have to be in business
The heart of the heat pump – refrigeration system – very little difference between manufactures as far as components – we weren’t going go away from the scroll compressor for example
High heat output – with Energy Star, high COP’s and EER’s have driven heat outputs down
COP is an easy measure for a homeowner to compare but at the cost of comfort
We wanted to meet ES – just above the bar and then focus on comfort
Think of the fit of hoods and doors of cars from 30 yrs ago
