Founder - Evolved Thermal Energy, Pres. - Ontario Geothermal Assoc. I help home & building owners make the transition to renewable thermal energy (Heat Pumps).
@danielfoch Has there been analysis on economic benefit over the life cycle? Obviously part of the “cost” is economic benefit to those designing and constructing the project, jobs etc. we often forget benefit over lifecycle; let’s be pragmatic in our assessment.
@janrosenow@patozsu@RegAssistProj This is where the value of GSHPs really shine - reducing grid peaks, builds steady base load. In reality either thermal energy networks where load diversity exists or multi source heat pumps ashp/gshp should prevail.
@JimMurp77852985@dsjost@liberal_party@s_guilbeault There the $40,000 (up to) interest free 10 year greener homes loan. A good tool for heat pump or solar projects. This is not an endorsement to use it, I’ve just seen many have success with it, lowering costs while investing in their own long term energy source. Kind regards.
@janrosenow@nesta_uk I wonder what the impact is on the early prevalence of GSHPs and grid capacity? In Canada once a ground loop is installed homeowners generally don’t abandon when HP is replaced so there would be a cumulative effect of high peak COP GSHPs in Sweden. Any grid stats available?
@CathNoakes Often missed in the discussion is the fact that the investment put into a ground heat exchanger is non-depreciating. If cash or credit facilities are available to support the construction costs, GSHP will net the best total value.
@br_haley@WabKinew Agree. Adding GSHPs to homes provides 3.5-4.0 COP during peaks, at scale provides incredibly cost effective way to electrify home heating/hot water. Ground loops are DERs - a watt saved is a watt generated. Future goes to most heat generated per watt used. GSHP wins that game.
@energysmartwv Why I focus all my efforts on Geo (GSHPs). Drown out the noise, focus on something good, if implemented at scale can drastically change the world. Challenges for sure but society gets so much better when our *peak* thermal energy needs are renewable sourced at point of use
@CAHiggins@DaikinApplied@HRAI_Canada We don’t see a lack of support with A2W, we are having some other challenges but support is not one of them. We work our products through our contractor network, we provide training, design and install support. Happy to chat on it.
@CAHiggins@DaikinApplied@HRAI_Canada Agreed, the good thing is we don’t need to wait for the Altherma for those types of systems, we’ve already got Air-to-Water system in market that are more than adequate for Infloor/embedded slab, fan coil and DHW applications.
@JohnPasalis Put LED lights on the gas meters right there next to the front door. Probably can smell the mercaptan as you walk past everyday. Point being, in this type of build, we have to put a little more brain power toward the thermal energy systems. Combustion is unnecessary.
@SteveSaretsky Furnace oil has been hit particularly hard in recent years, as a commodity, it’s price inflation significantly outpacing other fuels…in that light the carve out makes some sense to give those people time to switch, using whatever rebate program works best for them.
@glynhudson@Viessmann@Damon_BPHR That’s really interesting. Can you post the specs. On both units or at least the model numbers? Curious if the GSHP has variable compressor / same refrigerant / EVI? Or what the ASHP has under the hood?
@annarobertsmp Thats a bit of a twist on the truth. Yes, more than the “gas supply charge” but that charge comes with delivery and other fees, always. The cost of gas is inclusive of all those fees. This also excludes factoring in the effect of carbon rebate.
@FinanceLancelot That’s such an uninformed statement. And, I don’t think anyone is arguing the climate hasn’t shifted before. Just now we have tremendous populations at risk. But whatever, thanks Miami for the good times.
