Indirect vs heat pump water heater
We have natural gas powered radiant heat. We also recently installed a 14 KWh array of solar panels on our house. We live in Illinois and the state (despite being broke) passed some pretty insane incentives. We wound up paying about $6K for solar panels that had a total sticker price in the mid $30s.
I’d like to replace our hot water heater and I’m looking for thoughts on which would be better & more efficient between an indirect powered by the boiler and a heat pump powered (in large part) by free and clean solar . I’m leaning toward a heat pump because a) it reduces our carbon footprint (I’m assuming) and b) I like the added benefit of it serving as a dehumidifier in the summer months. We have frigid cold well water (despite being 13 miles from downtown Chicago) so on hot, humid days the pipes sweat a bit even when the AC is on. I’m also mildly worried about an indirect competing for BTUs with our radiant on cold days. We hit -17 F last winter.
Any thoughts/feedback would be greatly appreciated.
