I have gone through 2 L10's and I love them. If you do not drain them well before winter the copper cool will rupture. I use them on my concessions trailer paired with a shurflo diaphragm pump and it works awesome. You can get a shurflo pump in 12 or 120 v versions. They are on demand pumps so when they sense a pressure drop they kick on. Works very we'll mates to this unit. My only gripe is that they are susceptible to losing fire in the wind and the water temp then fluctuates.
