The Megaflo Eco SystemReady 145SB Indirect Unvented Hot Water Cylinder is a 145 litre indirect unvented hot water cylinder from Heatrae Sadia. It arrives pre-plumbed, with the controls and safety components already fitted, which takes a significant amount of time off the installation. It is rated at 3kW, carries a B energy rating and comes with a 2 year warranty.
It is an indirect cylinder, so it needs a boiler or heat pump to heat it; being unvented, it must be installed by a G3 qualified engineer and needs a discharge pipe to an outside wall. Both are explained in full under the Q&A tab.
At 145 litres this typically suits a 2 to 3 bedroom home with one bathroom, and a household of three to four people. Stored at 60C and blended down to a usable 40C, 145 litres delivers roughly 240 litres of hot water, enough to cover a bath and a shower in the same evening with capacity left for basins and the kitchen.
Recovery time here is 24 minutes, so the cylinder returns to full temperature quickly between uses.
Adjust from that figure for how the hot water is actually used. High flow showers and consecutive baths both argue for the next size up, while a household that rarely fills the bath will find the size below perfectly adequate.
One figure worth thinking about before choosing a position: 145 litres of water weighs 145kg, so once filled this cylinder puts at least 145kg onto the floor beneath it, plus the weight of the unit itself. That is rarely an issue at ground level, but for an upstairs cupboard or a loft it is worth confirming the floor can take it.
If you are not certain this is the right one, the Product Advisor walks you through the choice a question at a time. You are also very welcome to call us on 01934 253600.
