@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.

The high-speed train between Quebec and Toronto will cost more than 100 billion, according to information from La Presse... and could reach almost 200 billion if extensions are added along the way. lapresse.ca/affaires/2024-…

@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.

Grid constraints are the next frontier of the energy transition. How can we make better use of the grid we already have and minimise costs? My colleague @patozsu at @RegAssistProj put together this helpful toolbox: raponline.org/toolkit/rip-fi…

@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.

@dsjost @liberal_party @s_guilbeault We installed a heat pump and there is no rebates available because we're not Enbridge customers.

Just got our first propane fill up at the new house. $778. plus $160 Carbon Tax the HST for another $123. Almost $300 in tax for home heating or 36%. Don't tell me about getting back more than I pay please. @liberal_party @s_guilbeault

@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?

Sweden is a global heat pump leader. How have they managed to phase out fossil heating oil and deploy millions of heat pumps over a period of 20 years despite having one of the coldest climates in Europe? I will speak about this when I open this @nesta_uk event in London in two weeks: nesta.org.uk/event/what-can…

@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.

Manitoba @WabKinew says energy efficiency most affordable "Probably the most affordable way for Manitoba to add this is for us to be looking at some combination of retrofits on home heating and doing upgrades on existing electrical generation stations" cbc.ca/news/canada/ma…

@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

I hate being so pessimistic as a natural optimist. I have been thinking about the future, and it's just so bleak to me right now on a societal basis. Worrying about climate is really bad for the soul.

@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.

I would welcome to hear your experience with a2water retrofits. I have tried 6 a2w retrofits, 5 failed for 2 reasons. 1. Cost of existing product is too high. 2. there is a lack of full system support from mfr's, so we end up with 3+ companies/trucks on site to do the work. Daikin's offer changes that.

Listening to @DaikinApplied at @HRAI_Canada (Heating, Refrigeration and Air Conditioning Institute of Canada) heat pump symposium talk about their new air to water system up to +70C water in -28C outdoor temperature. Delivering space heating, cooling and domestic hot water. all refrigerant is factory sealed in the outdoor unit.

@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.

@JeffwHunter @DaikinApplied @HRAI_Canada In my city we have lots of in floor/hydronic slab. So it's perfect. With regards to cop, I don't have that figure, the coldest (in last 60 y)it gets in our area is -15C. I'll see what I can find.

@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.

A bungalow in East York has been redeveloped into a small condo with (what appears to be) 4 units. This link is for the biggest unit, 3 bedrooms and 4 bathrooms, listed for $1.6M 1/ realosophy.com/listing/3-319-…

@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.

Families get back more than they pay but also we’re pausing the carbon tax in Atlantic Canada because people can’t afford it. Lol

@PremierScottMoe Now this guy is marketing the rebate…

My response to the federal government threatening to take away the Carbon Tax Rebate for Saskatchewan families.

@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?

It's phenomenal how efficient ASHPs can be, I've just noticed that the @Viessmann installed by @Damon_BPHR is now outperforming GSHPs over the last 30 days and getting a COP of 8.0 at times today, and the average COP for today is 6.6, very impressive 👏heatpumpmonitor.org/system/view?id…

@h21_antony @KatyKing2 Thanks very much - Lovely home!

Why don’t more people put heat pumps in their front gardens? It’s not prohibited by permitted development. Here are some other things that are as big as a heat pump that people put in their front gardens

@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.

BREAKING NEWS Canadians are now paying more in carbon tax than the actual cost of gas. How will Justin Trudeau explain this to my constituent?

This is note for self for later review. latitudemedia.com/news/can-this-…

@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.

Global warming is so bad right now that most of the U.S. has frozen over.

@robsmallshire @mikeasharp Not yet. But it makes a difference to power generation when scaling such systems. Those folks will care.

@mikeasharp No idea. Nobody here cares about that stuff.

Out heat pump is happily heating our home to +20°C while it’s -23°C outside. Such a great technology.
