When people weigh up heat pump vs solar hot water, they are usually comparing upfront hot water system price or cost, roof space and how they use power during the day. A quality heat pump hot water system can be the most efficient hot water system for shaded roofs or properties with limited north-facing area, while a roof-mounted solar hot water installation with a ground or roof tank shines on full-sun sites. For homes staying all-electric, a modern electric hot water installation paired with rooftop solar can still deliver strong savings compared with older, power-hungry cylinders.
To give a rough feel for savings, many Coleyville households can expect average annual bill reductions like:
• Old electric to heat pump hot water system: $350–$700 per year • Gas hot water to heat pump hot water system: $250–$600 per year • Gas hot water to solar hot water system: $250–$550 per year • Old electric to new electric hot water system with solar: $200–$500 per year

That pattern reflects growing local interest in electrification, getting off bottled or mains gas, and using the area’s strong solar resource to lock in lower running costs. As more homes add rooftop solar, pairing it with an energy efficient hot water system is becoming an obvious move.
