Independent advice before replacing fossil-fuel heating

Heating electrification is not simply a boiler replacement. A credible transition must bring together the building’s heat demand, emitter temperatures, electrical capacity, heat-pump performance, photovoltaic production, battery storage, controls and energy tariffs.

Altair Energy Partners provides independent technical and financial assessments for owners, investors, lenders, ESCOs and operators considering a transition from gas or other fossil-fuel heating to heat pumps and integrated electrical energy systems.

We establish whether electrification is technically feasible, financially justified and operationally robust—and whether it should be implemented in one step or through a phased transition.

The decision we help you make

The question is not merely whether a heat pump can be installed. It is whether the proposed system will deliver the required heat reliably, at an acceptable lifecycle cost, without creating avoidable electrical peaks or relying on unrealistic assumptions.

Our assessment tests:

• the building’s measured heat and electricity demand;
• heat loss, operating temperatures and the suitability of existing emitters;
• realistic seasonal heat-pump efficiency rather than catalogue COP alone;
• electrical connection capacity and peak-demand implications;
• the contribution of on-site photovoltaic production;
• whether battery storage creates measurable operational or financial value;
• tariff exposure, controls and load-shifting opportunities;
• capital expenditure, incentives, maintenance and lifecycle economics;
• full electrification, hybrid operation and staged transition options.

An integrated assessment framework

1. Building and heating baseline

We review consumption data, operating schedules, heat-production assets, distribution temperatures, emitters, domestic-hot-water requirements and known building constraints. Where reliable measurements are unavailable, we identify the data required before an investment decision can be defended.

2. Heat-pump suitability

We assess heat-source options, required capacity, seasonal performance, part-load behaviour, redundancy, noise, space and hydraulic integration. Particular attention is given to flow temperature: a technically possible heat-pump installation is not necessarily an efficient one.

3. PV, storage and controls

Photovoltaic production can reduce imported electricity, but its seasonal profile does not naturally match winter heating demand. Battery storage can shift energy within the day, not from summer to winter. We therefore model its actual contribution instead of assuming that every heat-pump project requires a battery.

4. Electrical infrastructure

We examine connection capacity, coincident peaks, transformer or switchgear constraints, metering and the role of an energy management system. The objective is to avoid solving a heating problem by creating an unmanaged electrical one.

5. Financial assessment

We compare the existing heating baseline with credible transition scenarios using transparent assumptions for tariffs, seasonal performance, self-consumption, maintenance, replacement cycles and residual gas costs. Sensitivities show which assumptions genuinely determine the result.

What you receive

• technical baseline and principal constraints;
• heat-pump and integration concept;
• comparison of full, hybrid and staged transition options;
• PV and battery-storage contribution assessment;
• electrical-capacity and control requirements;
• CAPEX and lifecycle-cost comparison;
• principal risks, sensitivities and information gaps;
• a clear recommendation and implementation roadmap.

Independent of equipment vendors

Altair Energy Partners does not begin with a preferred heat pump, battery or installer. We begin with the building, the data and the investment decision. This gives clients a defensible basis for procurement, financing and project delivery.
