Realyze Ventures’ Post

Great Post by Realyze Ventures on the efficiency levels realized by modern heat pumps. Three key messages: 1) Analyzing empirical data (factfulness) helps cool down heated debates, and repeatedly demonstrates why heat pumps will become the dominant heating technology around the world. You can't debate physics. 2) We must end gas and oil heating now. It's massively wasteful both in terms of money and emissions, and it comes with a backpack full of nasty geopolitical risks. 3) When switching to a heat pump, you better make sure you choose the right installer! As you can see in the data, there are huge differences between systems in the top and bottom percentile (3x!). This may arise from the selection & sizing of the HP itself, the design & planning of the peripherals, the installation, the setup, and the asset maintenance & optimzation. This may cause several thousands of EUR more or less in homeowners pockets! Based on the continuous monitoring of COP data from our Vamo #heatfleet (TM) (among 50+ additional parameters) we can safely say that our systems exceed even the best heat pumps analyzed in the study. If you'd like to learn how we do that, or join the #newheat revolution (as a partner or team member), feel free to reach out!

#Heat #pumps are probably the most economical solution for future #climate-#neutral heating, particularly when deployed centrally with #heating #grids. Berit Hanna Czock, Oliver Ruhnau, and I draw this conclusion in our new #working #paper: “A heated debate – The future cost-efficiency of climate-neutral heating options under consideration of heterogeneity and uncertainty”. We investigate in a case study for Germany which heating technologies are cost-efficient in a future climate-neutral energy system, given uncertainties in energy, technology, and infrastructure costs and heterogeneous settlement types and buildings. Infrastructure investment decisions have to be made today because the transformation towards new infrastructure might take decades. To me, the most interesting conclusions for policy makers are: ① The decision between decentral and central heat pumps requires a case-by-case analysis. In Germany, making this choice should be the focus of the municipal heating planning (#Kommunale #Wärmeplanung) processes, which are due in 2028. ② #Hydrogen boilers can be economical in rural settlements and villages, BUT ③ Given the high #uncertainty in the future hydrogen price and grid costs, hydrogen boilers seem to be a more risky option than heat pumps, which are less exposed to increased energy and infrastructure costs due to their high coefficient of performance ④ Synthetic natural gas does not seem economical despite the fact that #SNG could utilize existing infrastructure in the short term. I am very happy to discuss your thoughts or feedback :) You can find the working paper here: https://lnkd.in/eMxF7pyZ

𝐅𝐮𝐭𝐮𝐫𝐞-𝐏𝐫𝐨𝐨𝐟 𝐍𝐨𝐰 – 𝐑𝐞𝐝𝐮𝐜𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐂𝐚𝐫𝐛𝐨𝐧 𝐅𝐨𝐨𝐭𝐩𝐫𝐢𝐧𝐭 𝐢𝐧 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧 The single most effective way to decarbonize your building will be to replace your fossil fuel burning heat source with a commercial heat pump powered by renewable electricity. Generally speaking, heat pumps alone are unlikely to meet the calorific demand satisfied by an oil or gas-powered heat source. Additional fabric improvements will be required to reduce demand enough for a heat pump to meet the performance requirements. Fabric upgrades could include secondary glazing or glazing unit upgrades and improved insulation to external walls and roof.   Interested?

Heat Conversion Design Using Peltier Thermo-electrics with Greenhouse Effect Heating System and Mobile Nitrogen Cooler Following the Sun Position

Heat mapping is the first step in developing strategic plans for the transformation of district heating systems. #LIFEProgramme funded #SET_HEAT project is doing this for #Bucarest, #Opole, #Vilnius, and #Zagreb and other, saller systems.  Preliminary results show that in some cases meeting the criteria for an efficient district heating system according to EED requirements can be  extremely difficult in a densely urbanised area. Without decarbonised fuels, it will be almost impossible to meet the criteria of effcient systems in 2050.

The benefits of geothermal heating and cooling are many: environmental friendliness, reduced cost, and high efficiency, to name a few. You've probably heard of ground-source heat pumps before, but... do you know what a ground-source heat pump really is? It’s essentially a refrigerator, and works off of the vapor-compression cycle.

Rise of large-scale heat pumps in #DistrictHeating – what to do about harmonics in the grid? District heating systems are undergoing a significant transformation with the integration of large-scale heat pumps. This shift offers a more sustainable and energy-efficient approach compared to traditional fuel-based models. While the adoption of heat pumps is a promising development, careful consideration needs to be given to infrastructure challenges: The increased power demands and unique electrical characteristics of heat pumps can impact power quality and introduce harmonics into the grid. Addressing these challenges is crucial for successful project implementation. Read our latest article to learn how to avoid common mistakes! #heatpumps #energysupply #energyefficiency

Heat pumps offer electric, low-carbon alternatives to gas furnaces, boilers, and air-conditioning units, acting as an all-in-one heating and cooling system. This technology could potentially reduce building-related heating and cooling emissions by up to 20 percent, but not all real estate professionals utilize them. Our latest report 'Pumping Up Sustainability: Myth-Busting Heat Pumps in Commercial Real Estate' dispels several myths surrounding #heatpumps and provides helpful data to encourage the use of heat pumps.
