The Problem

High energy consumption and carbon emissions.

Hotels, hospitals, nursing homes and large institutions need hot water around the clock. That relentless demand drives high energy use, heavy carbon emissions and rising costs — and most sites still meet it with legacy, fuel-based plant rooms.

The scale of it

Heat is expensive, constant and carbon-heavy.

For buildings that never stop, producing heat and hot water is one of the largest operating costs and one of the biggest sources of emissions.

Why it happens

Round-the-clock demand, met by legacy boilers.

Complex buildings can't turn the heat off. Guests, patients and residents need reliable hot water and warmth every hour of every day — so the plant room runs continuously, often on ageing, fuel-based equipment with limited visibility or control.

The result is wasted energy, exposure to volatile fuel prices and emissions that are hard to measure, let alone reduce.

The legacy plant room

Boilers burning diesel, mazut or LPG create waste, high costs and CO₂ emissions.

Fuel-heavy systems running 24/7 to guarantee supply
Reactive maintenance and little real-time visibility
High exposure to energy-price volatility
Emissions that are difficult to track or verify

And where a boiler has to stay, Dotz Energy can capture part of its CO₂ at the flue — cutting emissions even before the plant is replaced.

Built for complex energy users

The buildings that carry the heaviest heat loads.

From hotels to whole villages on a single central plant, the same continuous-demand profile shows up across the most energy-intensive building types — exactly where AI-led optimisation has the most to give back.
