Marco MT25 Water Boiler
The MT25 holds 25 litres ready to draw, which is the point of it: somewhere that empties a boiler in one go. Conference breaks, function catering, staff canteens and busy hotel breakfast service all pull hot water in waves rather than steadily, and a smaller boiler spends that time recovering while a queue builds.
It is the high volume option in the MT range, sharing the same controls, tank insulation and tap height as the smaller models.
Key features
- 25 litre immediate draw-off – serves a full sitting without waiting on recovery.
- Step-Fill refill – refills in short controlled bursts rather than all at once, so cold incoming water does not drop the tank temperature mid-service. Switch to continuous fill when you need volume back faster.
- Live temperature display – shows the actual tank temperature, so you know it is ready rather than guessing.
- Insulated stainless steel tank – holds heat between draws, which keeps the element off and the running cost down.
- 238mm tap-to-tray clearance – takes tall takeaway cups and pouring kettles without tilting.
- Removable drip tray – lifts out for cleaning.

Installation
The MT25 is plumbed in and needs a 3/4″ BSP cold feed and a 13A supply. We recommend fitting a water filter on the incoming supply, particularly in hard water areas around the South East, as scale is the main thing that shortens a boiler’s life. At this capacity a filter is worth doing properly – call us on 0800 442299 and we will size one to your water and throughput.
