A fantastic report by Brattle Group on the value of VPPs.

Heating water for potable use is the second largest demand for #energy in any structure with bedrooms and bathrooms. Most water heating systems in use today operate at 65%-85% efficiency. #heatpumpwaterheaters provide the same service while using ~25% of the energy (250%-300% efficiency) compared to any other method. A #HPWH system always includes hot water storage. In multifamily buildings, the hot water storage tanks are quite large; 800 gallons (3,028 liters) pairs with a 250,000btu/hr (73kW) HPWH. For Time of Use rate structures or #Demandresponse the HPWH can preheat using renewable energy during times of low grid demand, and remain off through the grid peaks. This combination of #efficiency and shiftable load provides massive #carbon emissions reductions and operational cost benefits to the occupants and the building owner.

This is a Piping and Instrumentation Diagram of a HPWH system.

We had a great crowd today at The Upper Midwest Home Performance Tradeshow and Conference. Eager energy professionals ready to take on #heatpumpwaterheaters

Given the importance of getting it right, I have to say it again: Okay, we are here #EnergyTwitter, but here, it is #EnergyMastodon

I'm heading to Minneapolis to the Upper Midwest Regional Conference and Tradeshow to train efficiency minded HVAC and plumbing contractors on the benefits of #HeatPumpWaterHeater technology to combat #climatechange by eliminating emissions relating to water heating.

#Electrification experts across the country recognize the potential of HPWHs:
- Electric heat pump water heaters offer the only approach to heating water at an #efficiency greater than 100%.
- use 1/4th or less energy overall compared to #fossilgas
- larger storage inherent in HPWH systems allow the heat pump to remain off during utility peaks, which coincide with hot water demand, providing valuable #demandresponse capabilities

Picked up some gently used gear today at the ski swap. My first time purchasing new skis in 22 years. I've been riding my 22 YO Soloman TenTwentys hard. Time to turn them into a chair or something.

Hello there. I'm super excited to be here! Seeing the feed and layout here is pretty exciting.
