Heating water with electricity is three times more expensive than heating it with gas in my market (The Netherlands). That turns a monthly bill of 60 EUR for gas warming into a bill of 180 EUR if you just switch like-for-like. A 3:1 ratio. Ground heat-pumps are being championed as a cost effective replacement for keeping houses warm. They provide a 4:1 heat:electricity ratio so have lower running costs than gas. They can also be attached to sun panels and can work with storage heaters (heat the water when the sun shines, use it when it doesn't). Unfortunately pumps are expensive and very invasive to install in existing houses - you need to dig gardens up to lay the pipes and installation for an average house is about 15-20k EUR ($17k-$23k).
