Hot Water Heat Pumps in Hawke's Bay by Alchemy Plumbing
Upgrade Your Heating System with Haier Hot Water Heat Pumps in Hawke's Bay
Hot water heating can be pricey, but Haier heat pumps change that. They move heat from the air into your tank using R290 refrigerant, not just electricity, slashing energy use by around 70–79 % compared to traditional electric heaters
Read on to understand the benefits of modern hot water systems and why they are a worthwhile investment for your home.
What Are Hot Water Heat Pumps and How Do They Work?
Hot water heat pumps use electricity not to generate heat directly, but to move heat from one place to another—making them far more energy-efficient than traditional hot water cylinder systems.
These systems extract heat from the ambient air and transfer it at a higher temperature into your home’s hot water tank.
This process is not only eco-friendly but also cost-effective, as it can significantly lower power bills over time.
Tanks come in 200 L, 250 L, 330 L, feature triple-layer corrosion protection, quiet operation (~43 dB), and have a 5-year parts and labour warranty (7 years on cylinder)
